4grayandClaude Fable 5 2521092753 fix(epg): resolve second-order review findings on the mapping follow-up
Two P2 issues Codex raised on the previous fixes:

- Unscoped program lookups could return the same programme twice now that
  the dedup index preserves per-source rows: the M3U timeline calls
  getChannelPrograms without sourceUrls, so two sources sharing
  channel/start/title both surfaced. Added toEpgProgams(), which collapses
  duplicate channel|start|title slots after mapping/validation, applied at
  every getChannelPrograms return.
- EpgQueueService.fetchEpg unconditionally cleared the in-flight marker in
  its finally, which could drop a marker a re-enqueued request took over
  after invalidate(). It now only releases the marker when the completing
  request still owns it (epoch unchanged), preserving per-stream dedup and
  concurrency accounting.

Tests: unscoped duplicate-slot collapse; stale request preserving a fresh
in-flight marker.
