        form should default to None

        if form is None, check if characteristic of field divides order of group. if so, it's the modular case, and we return the projection onto idempotents change-of-basis, i.e. the MFT. if not, use semi-normal form.

        I see, so "None" if the user doesn't specify, and we determine which form based on whether p|n!. Sounds good.

        gh-37764: ECM-related tests fail after an incremental build

        ### TL;DR:

        This is because setting the default ECMBIN=ecm is only done when using
        the configure test, but not when skipping the configure test because the
        spkg is already installed.

        ### Steps to reproduce:
        * ecm is not installed in the base os
        * Sage make distclean && make succeeeds
        * Tests succeed
        * re-running ./bootstrap && ./configure && make works
        * Tests now fail with PermissionError: [Errno 13] Permission denied: ''

        gh-37736: Reimplementing the Witt (Sym Func) change of basis, caches, and omega involution

        <!-- ^ Please provide a concise and informative title. -->
        <!-- ^ Don't put issue numbers in the title, do this in the PR
        description below. -->
        <!-- ^ For example, instead of "Fixes #12345" use "Introduce new method

        We reimplement the coercion from the Witt basis of symmetric functions
        to the $h$, $e$, and $p$ bases and their inverses by using the
        generating function identities and recursion for $w_n, h_n, e_n, p_n$
        and the mulitplicative basis property for the general shape (in
        particular, we attempt to minimize the number of multiplications and
        maximize the use of the cache by recursively splitting the partition by
        its smallest part). We cache the result using `@cached_method` instead
        of custom classes. We also deprecate the `coerce_*` inputs.

        We also take advantage that $\omega w_n = w_n$ when $n$ is odd to
        compute the omega involution. This extends to a faster computation of
        the antipode.

        The matrix constructor used to accept ``ring`` as argument to specify a
        the base ring of a matrix.
        It now takes ``base_ring`` instead. ``ring`` is still accepted but
        deprecated (I added a deprecation in the code).
        This is for unification (``base_ring`` is what users expect from their
        experience with other classes).
        This solves @mkoeppe's issue #33380.

        As discussed in
        https://github.com/sagemath/sage/pull/37589#issuecomment-2030456264, the
        Sage documentation system uses Sphinx to format the documentation in the
        terminal, for example in the help system.

        For the modularization project, a simple fallback for the case of Sphinx
        not being present was added.

        Here we declare the corresponding "extra" so that users can do `pip
        install sagemath-repl[sphinx]`.

        Checking if a matrix is nilpotent is a fundamental test that Sage is
        (surprisingly) missing. We check this by using the char poly.

        gh-37699: Add `approximate_closest_vector` to `IntegerLattice`, using Babai's nearest plane algorithm

        This PR implements Babai's nearest plane algorithm to find vectors close
        to a given vector in an integer lattice.

        I would appreciate if someone could verify the bound stated in the
        docstring, it is inferred from Babai's original paper but parameterized
        to use the `delta` parameter of the LLL algorithm.

        Ideas for improvements:
         - The doctest is currently the same as for `closest_vector`, this could
        be expanded
         - The `delta` parameter for LLL needs to be kept track of by the user.
        How "much" the basis has been reduced (i.e to how high a `delta` value)
        could be kept track of by the class and if a further reduction is needed
        for some given bound then it could be performed.

        gh-37687: provide a construction functor using a single functor for families

        We enable sage to find common parents also when symmetric functions are
        involved. In particular, we provide a functorial construction that takes
        a commutative (coefficient) ring and produces a (commutative) ring of
        symmetric functions over this ring.

        For Macdonald polynomials and other symmetric functions that involve
        parameters we cheat a bit: the categories should actually be commutative
        rings with distinguished elements (namely, the parameters). However,
        having these is very likely overkill.

        This is an alternative to #37220, relying on individual construction
        functors instead of passing around strings, and #37686, which provides
        an individual functor for each family.

        gh-37668: Wrong results in is_isotopic method of the Link class for certain chiral link

        <!-- ^ Please provide a concise and informative title. -->
        <!-- ^ Don't put issue numbers in the title, do this in the PR
        description below. -->
        <!-- ^ For example, instead of "Fixes #12345" use "Introduce new method

        The following result is wrong, since `K10_67` is a chiral knot:

        ```
        sage: L = KnotInfo.K10_67
        ....: L1 = L.link()
        ....: L1r = L.link().reverse()
        ....: L1.is_isotopic(L1r)
        True
        ```

        The problem is that the `get_knotinfo` method currently does not
        distinguish between all four symmetry mutants of a chiral knot or link.
        In the example, `get_knotinfo` detects both knots as *not mirrored* to
        the symmetry mutant of `K10_67` recorded in the KnotInfo database, as
        you can see from the verbose messages:

        ```
        sage: set_verbose(1)
        sage: L1.is_isotopic(L1r)
        verbose 1 (4365: link.py, is_isotopic) KnotInfo other: KnotInfo.K10_67
        mirrored False
        True
        ```

        The wrong conclusion in `is_isotopic` is that they must be isotopic.

        The idea in this PR is to replace the boolean `mirrored` in the output
        of `get_knotinfo` with the value of an enum representing all symmetry
        mutants for an entry of the KnotInfo database. Of course, this requires
        major revisions in the `get_knotinfo` and `is_isotopic` methods. The key
        to this is a new local method `_knotinfo_matching_dict` that builds on
        `_knotinfo_matching_list` and returns the matching list for all symmetry
        mutants.

        On the occasion of that revision, I also fix other wrong results for
        example this one of a multi-component link which is not amphicheiral,
        but reversible:

        ```
        sage: L = KnotInfo.L6a2_0
        sage: L1 = L.link()
        sage: L2 = L.link(L.items.braid_notation)
        sage: L1.is_isotopic(L2)
        False
        ```

        This bug is due to `get_knotinfo` returning the wrong mirror version for
        `L1` concerning `L6a2_1`:

        ```
        ...
        sage: L1.get_knotinfo(unique=False)
        [(<KnotInfo.L6a2_0: 'L6a2{0}'>, False), (<KnotInfo.L6a2_1: 'L6a2{1}'>,
        False)]
        sage: L2.get_knotinfo(unique=False)
        [(<KnotInfo.L6a2_0: 'L6a2{0}'>, False), (<KnotInfo.L6a2_1: 'L6a2{1}'>,
        True)]
        ```

        In addition to these fixes, improvements and corresponding adjustments,
        I correct some document formatting.

        gh-37667: Fix noexcept clauses (#37560)

        In #36507 I added a lot of `noexcept` clauses guided by a warning which
        is not quite right (see
        https://github.com/cython/cython/pull/5999#issuecomment-1986868208).

        A new warning in 3.0.9 shows the mistake (incorrectly added `noexcept`
        clauses). This broke some doctests (#37560) and a workaround was
        implemented for 10.3 (#37583) since we were too close to release.

        This PR now does the proper fix, removing all the incorrect `noexcept`,
        and also adding a few missing `noexcept`.

        Note: if one tries this PR with cython <= 3.0.8 it seems it's wrong in
        the sense that it will show 40k more warnings after the PR. These are
        *incorrect* warnings.

        If one uses cython 3.0.9 each of these 40k lines give a correct warning
        before this PR and an incorrect warnings after the PR, and there is no
        way to avoid 40k warnings.

        To confirm this PR is a good one, one needs to use cython 3.0.9 +
        https://github.com/cython/cython/pull/6087 or wait for cython 3.0.10. In
        this case, the warnings are correct and one will get 40k warnings before
        the PR and no warning after the PR.

        The last commit reverts the workaround from #37583 so we don't silence
        these warnings on `cython()` now that we have our own code right.

        @vbraun: this is "almost trivial" but touches too many files. Could we
        merge it in beta0 to avoid conflicts? I did this "kind of" automatically
        and I've been testing it for two weeks in almost all my builds. The
        changes made should not affect behaviour at all in the legacy mode we
        are using cython.

        gh-37640: Modified `.is_reduced()` of `binary_qf.py` to avoid square root computation

        Adapted the checks in `.is_reduced()` to avoid the square root
        computation, which fixes #37635. Furthermore added a non-singularity
        check.

        This adaption is based on the observation that $$|\sqrt{D} - 2 \cdot
        |a|| < b < \sqrt{D}$$
        if and only if $$b > 0, \ a \cdot c < 0 \text{ and } (a-c)^2 < D$$
        are all satisfied simultaneously (where $D = b^2 - 4ac > 0$).

        The above can be proven in a straightforward manner by taking squares
        and square roots while making sure that the numbers being squared are
        always positive, so that inequalities are preserved.

        Plain TeX users may remember `\bordermatrix`. Here we implement this as
        options of the `Matrix` class's `str` method.
        ```
                    sage: M = matrix([[1,2,3], [4,5,6], [7,8,9]])
                    sage: M.subdivide(None, 2)
                    sage: print(M.str(unicode=True,
                    ....:             top_border=['ab', 'cde', 'f'],
                    ....:             bottom_border=['*', '', ''],
                    ....:             left_border=[1, 10, 100],
                    ....:             right_border=['', ' <', '']))
                                ab cde   f
                             1⎛  1   2│  3⎞
                            10⎜  4   5│  6⎟ <
                           100⎝  7   8│  9⎠
                                 *
        ```

        Follow-up PR: As the guiding application for this feature, we equip
        finite-dimensional modules with basis with methods `_repr_matrix`,
        `_ascii_art_matrix`, `_unicode_art_matrix` that can be used as in this
        example:
        ```
                        sage: M = matrix(ZZ, [[1, 0, 0], [0, 1, 0]],
                        ....:            column_keys=['a', 'b', 'c'],
                        ....:            row_keys=['v', 'w']); M
                        Generic morphism:
                        From: Free module generated by {'a', 'b', 'c'} over
        Integer Ring
                        To:   Free module generated by {'v', 'w'} over Integer
        Ring
                        sage: M._unicode_art_ = M._unicode_art_matrix
                        sage: unicode_art(M)                            #

        gh-37497: remove zombie code

        We remove zombie code for solving linear systems over a finite field,
        which was (likely accidentally) created in #23214, but leads to errors
        when solving sparse linear equations over finite fields.

        This does not quite fix the issue, because we now fall back to generic
        code.

        Fixes #28586

        gh-37391: Make installation of "wheel" packages less noisy

        <!-- ^^^^^
        Please provide a concise, informative and self-explanatory title.
        Don't put issue numbers in there, do this in the PR body below.
        For example, instead of "Fixes #1234" use "Introduce new method to
        calculate 1+1"
        -->
        <!-- Describe your changes here in detail -->
        Some care for `build/bin/sage-spkg`, reducing unhelpful verbosity. In
        particular, for "wheel" packages (https://deploy-livedoc--
        sagemath.netlify.app/html/en/developer/packaging#package-source-types),
        there is no build step, so there is no point in talking about what C
        compiler is in use.

        Also saving a few lines of output (and making it clearer who does what)
        by prefixing the output from the various `spkg-...` scripts.

        Example:
        ```
        $ make packaging-no-deps
