Replace the hand-written inventory with scripts/gen-third-party-notices.ts,
verified fresh by a doc-sync leaf gate. Tier by declaring workspace area
rather than manifest section, so test-support runtime declarations stay
dev-only and every mountable plugin's dependencies are disclosed as
runtime; list the pnpm-patched packages; point the Python closure at
uv.lock. Re-record the translation-prompt snapshot the README link
invalidated.
