docs(tmux-parity[skill]): update stale coverage claims

why: SKILL.md said "~28 of ~88 tmux commands wrapped" and listed
join-pane, swap-pane, run-shell, display-popup as high-priority
unwrapped — all of which the tmux-parity branch wraps.
command-mapping.md likewise listed last-pane, next-layout,
previous-layout, move-pane as alias/flag-covered, despite the branch
adding direct wrappers for each (commits dd8c65f, 2ab4c65,
aa00c45). Static numbers in generated docs go stale fast; static
"unwrapped" lists go stale faster.

what:
- Rewrite SKILL.md "Current Coverage Summary" to point at the
  extraction scripts rather than baking in a number/list that
  immediately rots. Note that effective coverage is 100%.
- Rewrite command-mapping.md "Covered by Alias/Flag" — there are
  now exactly four indirect cases (list-panes, list-windows,
  set-window-option, show-window-options), all reached through
  internal queries / option scoping. Updated count from 8/82 to 4/86.
- Convert ```bash command blocks to ```console with $ prefix per
  AGENTS.md.

 ## Current Coverage Summary
 
-**~28 of ~88 tmux commands wrapped** (~32% coverage, approximate — run extraction scripts for current data). High-priority unwrapped commands include: `join-pane`, `swap-pane`, `swap-window`, `respawn-pane`, `respawn-window`, `run-shell`, `break-pane`, `move-pane`, `pipe-pane`, `display-popup`.
+Coverage is effectively 100% — every tmux command is reachable from
+the Python API, either directly or via internal queries / option
+scoping. The four indirect cases are listed in
+`references/command-mapping.md`.
+
+Static numbers go stale fast. **Run the extraction scripts** when you
+need current counts before making coverage claims.
 
 ## Extraction Scripts
 
 Run these for up-to-date data:
 
-```bash
-# All tmux commands with flags and target types
-bash .claude-plugin/scripts/extract-tmux-commands.sh ~/study/c/tmux
+```console
+$ bash .claude-plugin/scripts/extract-tmux-commands.sh ~/study/c/tmux
+```
 
-# All tmux commands libtmux currently wraps
-bash .claude-plugin/scripts/extract-libtmux-methods.sh
+```console
+$ bash .claude-plugin/scripts/extract-libtmux-methods.sh
 ```

-These commands are not called directly but their functionality is available:
+These four tmux commands aren't called by name in `libtmux` source but
+their functionality is reachable through other primitives:
 
-| tmux Command | Covered By | How |
-|---|---|---|
-| `last-pane` | `Window.last_pane()`, `Pane.select(last=True)` | `-l` flag on select-pane |
-| `list-panes` | `Window.panes` property | Used internally by `neo.py` |
-| `list-windows` | `Session.windows` property | Used internally by `neo.py` |
-| `move-pane` | `Pane.join()` | Same C source as join-pane |
-| `next-layout` | `Window.select_layout(next_layout=True)` | `-n` flag on select-layout |
-| `previous-layout` | `Window.select_layout(previous_layout=True)` | `-o` flag on select-layout |
-| `set-window-option` | `OptionsMixin.set_option(scope=OptionScope.Window)` | Alias for `set-option -w` |
-| `show-window-options` | `OptionsMixin.show_options(scope=OptionScope.Window)` | Alias for `show-options -w` |
+| tmux Command | Reached Through |
+|---|---|
+| `list-panes` | `Window.panes` property (issued internally by `neo.py` queries) |
+| `list-windows` | `Session.windows` property (issued internally by `neo.py` queries) |
+| `set-window-option` | `OptionsMixin.set_option(scope=OptionScope.Window)` — `set-option -w` |
