Resolves #12176

The release-notes index generator release.mjs was never migrated to the chunk-N release-notes shape that ReleaseNotesSyncer (#11405) produces — its sibling tickets.mjs was migrated in #11287/#11295 but the release index was out of that scope. It globbed *.md non-recursively (matching zero files once release-notes moved under chunk-N/) and emitted flat, reconstructed paths. Result: the committed releases.json paths now 404 (e.g. v12.1.0.md lives at chunk-2/), and any regeneration would silently empty the index. This switches to a recursive glob + path.relative (mirroring tickets.mjs:130) and commits the corrected releases.json.

Evidence: L2 (ran create-release-index — 166 release paths, all resolve to on-disk files; recursive scan confirmed finding chunk-1 + chunk-2) → L2 required (close-target ACs are index-correctness + path-resolution, fully tool-verifiable). Portal view is path-agnostic (await fetch(path), proven by the already-working tickets view), so no runtime-only residual. No residuals.

Deltas from ticket

• Fixed a pre-existing date: date verbose-key form at release.mjs:100 (surfaced by the check-shorthand pre-commit hook, which scans the whole staged file) → ES2015 shorthand. Mechanical, in-file, required to commit the touched file.

Test Evidence

• node buildScripts/docs/index/release.mjs → Found 166 releases. (was 0 with the non-recursive glob).
• Path-resolution check over the generated releases.json: leaf entries=166 missing=0 parents=5 — every emitted path resolves to a real file on disk.
• Spot-check: v12.1.0 → resources/content/release-notes/chunk-2/v12.1.0.md (exists; previously the flat path release-notes/v12.1.0.md 404'd).
• Major-version tree grouping + descending-semver sort preserved (v12 expanded first, 5 parent nodes).
• git diff --check clean; check-whitespace + check-shorthand pre-commit hooks pass.
• No existing spec for buildScripts/docs/index/* generators (consistent with the repo convention — these are verified by running, same as tickets.mjs).

Post-Merge Validation

• Portal release-notes view renders and content loads for a recent release (e.g. v12.1.0) on the deployed portal — symmetric with the already-working tickets view; index correctness is verified pre-merge.
