Move to aixgo-dev/code and rename the product to Aixgo Code (#137)

The repository moved from simplycubed/code to aixgo-dev/code and the
product is now Aixgo Code. Nothing about how the agent works changed;
every change here is a name, applied everywhere the old one appeared so
no half-renamed path is left to fail at runtime.

- Module path github.com/simplycubed/code -> github.com/aixgo-dev/code,
  and every import with it.
- Binary cmd/simplycubed -> cmd/aixgo, so the CLI is `aixgo`.
- Adopter config .github/simplycubed.yml -> .github/aixgo.yml. This repo
  runs on itself, so its own copy moves too and now reads
  appName: aixgo-code with labelPrefix: ax.
- Reusable workflow and templates renamed to aixgo.yml,
  aixgo-caller.yml, and aixgo-selftest.yml, in .github/workflows/,
  docs/templates/, and the embedded cmd/aixgo/*.yml.tmpl.
- Repository variables and secrets take the AIXGO_ prefix. A value read
  by the old name is not read at all, so an unmigrated repo fails on a
  missing value rather than using a stale one.
- Default labelPrefix sc -> ax, so the lifecycle is ax:go through
  ax:done. Scratch paths follow: .aixgo/ and the aixgo/ledger branch.
- The generated commit and pull-request marker is Aixgo Code.
- Release pins move to v0.4.0 and CHANGELOG.md records the move as
  breaking, with the re-run instructions. Sections for v0.3.0 and older
  keep the old names: they describe what was true then.
- The README banner image was SimplyCubed-branded artwork, so it and
  docs/assets/ are removed. The lineage section records that this was
  published as SimplyCubed Code at simplycubed/code.

Tags before v0.4.0 stay in history but declare the old module path, so
they are not installable as github.com/aixgo-dev/code.

 This project does **not accept external code contributions**, so pull requests are closed with a pointer to [CONTRIBUTING.md](../blob/main/CONTRIBUTING.md). That is the project's governance model, not a judgment on the work: the codebase's provenance is kept clean because the tool runs with write access inside other people's repositories.
