Complete the distribution metadata and publish flow for the unscoped
`gitea-axi` package:
- add `repository`, `homepage`, and `bugs` to package.json
- add `publishConfig` (public access, npmjs registry) so `npm publish`
needs no extra flags
- replace `prepublishOnly` with `prepack: npm run build`, so both
`npm pack` and `npm publish` rebuild `dist/` first
- document the single-command flow in PUBLISHING.md
- add a packaging smoke-test tier (`test:pack`) that packs the real
tarball, installs it globally, and drives the installed binary
(`--help`, dashboard header, and `setup` finding the bundled skill)
- CONVENTIONAL-COMMITS.md: vendored spec (v1.0.0); CLAUDE.md requires
agent-written commits to follow it
- tasks 0002-0020: remaining task breakdown of the gitea-axi spec
(0019 reframed around the three-tier test taxonomy: unit,
integration, end-to-end)
- spec, CONTEXT.md, and ADRs 0006/0007/0011: pending design
refinements from the planning sessions
