docs: add axi-axi to community catalog - #113

Intent

Add the axi-axi package (https://github.com/CodyEngel/axi-axi) to the AXI community catalog so it shows up in the generated README.md and axi.md catalog tables.

What Changed

• Added an axi-axi entry (author CodyEngel, domain "AXI authoring") to the community section of catalog.yaml, the single source for the AXI catalog.
• Regenerated the generated:catalog-community regions of README.md and docs/index.html so the new row appears in both the README table and the axi.md site table.

Risk Assessment

✅ Low: A three-file, docs-only catalog addition that follows the documented contributor workflow exactly, with generated regions consistent with what the generator would emit and no source-verifiable defects.

Testing

I exercised the catalog change on all three surfaces it touches. The docs:check CI gate passes, meaning the committed README.md and docs/index.html tables are byte-exact regenerations of catalog.yaml; a negative test (dropping the axi-axi entry) made that same check fail on both files, proving the rows are genuinely generated from the new entry rather than hand-typed, and the worktree was left clean after restoring. I then served docs/ locally and screenshotted the real axi.md page, showing axi-axi as the final community-catalog row with the correct author, domain, description, and a link to github.com/CodyEngel/axi-axi (which returns HTTP 200). README.md has no rendered screenshot because its end-user surface is GitHub's own markdown renderer, which isn't reproducible offline without sending content to an external API; the identical catalog data is shown rendered in the axi.md screenshots, and the README row is verified through its generated table region plus the byte-exact docs:check gate. Everything passed with no issues found.

• Evidence: axi.md community catalog — full table with axi-axi as the last row (rendered site) (local file: /var/folders/h0/hd2bmc2524z2fz14zcl1p4400000gn/T/no-mistakes-evidence/01KY8K1RATY258V0NX239V9WWG/axi-md-community-table-full.png)
• Evidence: axi.md community catalog — close-up of the axi-axi row at full reading size (local file: /var/folders/h0/hd2bmc2524z2fz14zcl1p4400000gn/T/no-mistakes-evidence/01KY8K1RATY258V0NX239V9WWG/axi-md-community-catalog.png)
• Evidence: axi.md catalog section — COMMUNITY heading and column headers in context (local file: /var/folders/h0/hd2bmc2524z2fz14zcl1p4400000gn/T/no-mistakes-evidence/01KY8K1RATY258V0NX239V9WWG/axi-md-catalog-full-table.png)

$ pnpm run docs:check       # the docs-check CI gate: regenerates from catalog.yaml and fails on drift
docs:check ok — generated regions match their sources

# --- Negative test: temporarily drop the axi-axi entry from catalog.yaml ---
$ node scripts/generate-docs.mjs --check   (with axi-axi removed from catalog.yaml)
error: README.md is out of sync with catalog.yaml/principles.yaml
error: docs/index.html is out of sync with catalog.yaml/principles.yaml
help: run `pnpm run docs:gen` and commit the result
exit code 1   -> both tables really are generated from the catalog entry (catalog.yaml restored afterwards; git status clean)
