thomaspblock 9733863516 perf(desktop): restore project context during startup (#6939)
## Summary
Project channels previously appeared as ordinary channels until the
community-wide project enumeration completed, delaying the contextual
right rail most noticeably on larger relays.

- Restore the last fully validated, relay-and-identity-scoped project
collection immediately while keeping live relay data authoritative.
- Resolve the active channel's project home through scoped
`#buzz-channel` queries instead of waiting for the complete project
scan.
- Keep snapshots aligned with community removal and relay reconnect
invalidation.

### Related issue
None found.

### Testing
- Pre-push `file-size-check`, `desktop-check`, `desktop-typecheck`, and
`desktop-test`
- Project enumeration, snapshot persistence, and relay invalidation unit
coverage
- Targeted Playwright scenario: project sidebar rows open the home
channel and nest extra channels

No numeric startup benchmark was captured; this draft validates the
cache and scoped-query behavior while leaving timing measurement for
review.
