docs: add cargo-axi to community catalog - #114

Speaking as Kun's firstmate: I reviewed the diff (catalog.yaml plus generated README.md / docs/index.html only) and independently inspected the package.

Independent source review at pin ca4b3d9cabc7938fd478dd92ffb1940ee3f1c70b (tag v0.1.0, also current main HEAD). Files read: src/main.rs, src/cli.rs, src/lib.rs, src/output.rs, src/hooks.rs, plus the recursive tree at that revision. Direct observations at that revision:

• TOON via toon_format::encode_default at the output boundary only (src/output.rs)
• cargo axi no-args home prints bin, description, workspace summary, and a compact default-member package list with a hint to list all
• packages defaults to 3 fields (name, version, targets) with --limit (default 100) and --full; total is always included
• unknown flags rejected per command with valid flags listed; structured {error, help} on stdout; exit 0/1/2
• principle 7 held: cargo axi setup hooks <install|inspect|remove> --app claude|codex|opencode|all merges/repairs JSON hooks (does not overwrite unmanaged files), PATH-vs-absolute executable, session start/end
• generated skills/cargo-axi/SKILL.md is checked against CLI metadata
• principle 10 --version / -v / -V not held (treated as unknown command). Help pages and home identification otherwise hold. Same class of gap docs: propose forgejo-axi for the community catalog #150 treated as partial, not the blocker.

VISION.md per-rule:

• AXI principles: aligns for admission at this pin (principle 7 held; --version noted as a remaining P10 gap, not blocking).
• Catalog: aligns. Inspected source at ca4b3d9 satisfies applicable AXI principles for a community catalog add. Description matches the inspected surface.
• SDKs: aligns (docs-only catalog add; no SDK change).

I resolved the catalog conflict file-only (catalog.yaml + docs:gen) and pushed to the contributor fork. Admitting and merging if CI is green.

Speaking as Kun's firstmate.

This catalog entry landed via last-resort port #156 (squash merge 910c24b9cad070cf7fe80e54c3634a80d7537fad) because #114 stayed CONFLICTING on the fork after a file-only resolve + docs:gen push. No rebase was requested. Closing this original as redundant now that cargo-axi is on main.
