bflatasticandClaude Opus 5.5 26c714db7f M4.14: content-keyed RAM preview frames; proxies in the disk cache's content key ...

- FrameKey's identity is the comp's content (frames::comp_content), not the project revision:
  an edit keeps the cached frames of comps it doesn't touch and undo finds the frames of the
  state it returns to. The identity hashes the addresses of the comps a comp draws (~0.1 ms on
  the 1500-layer test project; the full content hash took ~117 ms), by value the footage, solids,
  proxies and project settings; with expressions, every item. Frames::content_of keeps a
  project snapshot per identity with frames (or in flight), so Arc::make_mut always copies an
  edited comp and its address can't be reused meanwhile; past 64 identities the least recently
  used go with their frames (long drags).
- drop_stale is gone (frames of other contents are evicted least-recently-shown first).
- disk_cache::comp_content_key covers items' proxies and Use Proxy (it served stale frames).
- Tests: frames (content keys, edits elsewhere and undo, bounded drags, in-place edit safety),
  ui_ram_preview (end to end), the disk cache proxy key. Docs: roadmap (M4 done), parity.
