Point offline source comments at split leaf guidance

[Fooftilly]

Summary

Follow-up to #319.

That PR split the former monolithic offline/PWA guidance into a small router plus bounded leaf contracts. A few production source comments still pointed at old section names inside docs/agent-rules/offline-pwa.md, which now serves only as the router.

This PR updates those comments to point directly to the leaf that owns the invariant.

Changes

• frontend/js/api.js
  • Positions coherence → offline-entity-coherence.md
  • browse projection coherence → offline-browse-protocol.md
  • Folder coherence → offline-folder-tag-coherence.md
• frontend/js/app.js
  • Folder cache-shape comments → offline-folder-tag-coherence.md
  • Playlist cache-shape comments → offline-entity-coherence.md
• backend/db_manager.py
  • compact browse projection comment → offline-browse-protocol.md
• tests/test_agent_guidance_current.py
  • add a regression requiring these domain-specific source comments to point to leaf guidance rather than the offline-pwa.md router.

Scope

Documentation/comment-reference cleanup only. No runtime behavior, persistence, sync semantics, UI behavior, or API contracts change.

Validation

Normal PR CI should validate the focused guidance regression and confirm the comment-only production-file edits do not affect behavior.

📝 Walkthrough

Walkthrough

Source comments now point to offline documentation for browse catalogs, entity coherence, and Folder tag coherence. A test checks that the backend and frontend source files use the expected references.

The guidance links resolve, but the regression test may miss a wrong link on an individual comment. Tighten the per-comment checks; runtime behavior is otherwise unchanged.

High-Level Assessment

Direct leaf references suit domain-specific comments and the existing split-guidance structure. Keeping router references would make readers resolve outdated section names; adding a separate reference registry would be disproportionate to this comment cleanup.
