Add searchable PF4J 3.15.0 API reference

[Arinbus]

Summary

• publish a searchable PF4J 3.15.0 API reference at /api/
• replace the existing 2.4.0-only JavaDoc navigation page with links to the current reference and archived versions
• include a reproducible, version-pinned Doxygen → Moxygen → Sourcey build under sourcey-api/

Why

The current Reference page points only to PF4J 2.4.0 on javadoc.io. This adds a project-owned reference for the current 3.15.0 release with exact-source links, full-text search, stable canonical URLs, and llms.txt exports.

Reproducibility and scope

• PF4J release commit: 2ce777013963706c868b79da1483270e2690afab
• Sourcey: 3.6.5 (exact lockfile integrity)
• Moxygen: 2.1.12 (exact lockfile integrity)
• generated output: 97 HTML pages, 1,054 search entries, 933 links to exact source lines
• repository change: 201 generated /api/ files plus 14 build/source files; no workflow is added
• generated output is committed so the existing Jekyll/GitHub Pages path can publish it directly

Rebuild:

cd sourcey-api
npm run build:all

The build uses npm ci --ignore-scripts, checks out the immutable PF4J release commit, regenerates the site, copies third-party notices, and runs scripts/verify-output.py.

Verification

{"broken_local_links":0,"canonical_pages":97,"generator_pages":97,"html_pages":97,"search_index_entries":1054,"source_links":933,"status":"valid"}

Also verified locally:

• HTTP 200 for /api/, representative API page, search index, llms.txt, and OG image
• browser render and search behavior; zero console/JavaScript errors
• no private paths, credentials, cache files, or files over 1 MiB
• git diff --check passes

Licensing

The generated site includes Sourcey's AGPL-3.0 license text and a third-party notice with exact package integrity values. PF4J source links and the footer retain the project's Apache-2.0 attribution.
