docs: add pypi-axi to community catalog

[mstuart]

What Changed

• Added a pypi-axi entry to catalog.yaml's community list (name, url, author, domain, description).
• Regenerated the corresponding generated community-catalog regions in README.md and docs/index.html to include the new pypi-axi row.

Risk Assessment

✅ Low: Purely additive documentation change (one catalog.yaml entry plus its generated README.md and docs/index.html rows) with no source code, build, or release-process changes; content and table formatting are internally consistent with existing entries.

Testing

This is a docs-only change adding the pypi-axi CLI to the community catalog (catalog.yaml, README.md, docs/index.html). After installing workspace dependencies (pnpm via corepack, gitignored and removed afterward), docs:check passed, confirming no drift between catalog.yaml and the generated markdown/HTML regions for the new entry, and the generator's existing unit tests passed unchanged. No code paths beyond doc generation were touched, so no further evidence is needed.

Evidence: docs:check output confirming generated regions match catalog.yaml

docs:check ok — generated regions match their sources
EXIT:0
