feat(career): gigs frontend — poster, runner strip, summary, encore (#956)

* feat(career): gigs frontend — poster, runner strip, summary, encore

Career v3, WS3 (frontend half), rebuilt cleanly on merged main (v3-a/b/c
in) after git interleaved the structurally-similar canvas functions:

- Book a gig from any opened passport: /gigs/propose renders as a GIG
  POSTER (venue presents GENRE NIGHT, numbered bill) with re-roll and
  Save/Copy poster (natively-drawn canvas via blob-io, audible failure
  paths, slash-safe filenames).
- Play the gig: venue override + Venue viz handoff, then
  playQueue.start(..., {source:'gig'}) — the queue's auto-advance runs
  the set; zero new playback machinery.
- Floating gig strip (body-level, pointer-events none, z 35 per the
  chrome invariant) tracks set position and names what's next.
- Completion = song:ended with an empty queue → POST /gigs → summary
  poster overlay with per-song accuracies; encore fires the crowd
  celebrate + confetti (reduced-motion: neither). song:stop with a dead
  queue = abandoned (no log); end-of-song teardown (queue still active)
  must NOT abandon.
- Gigs played render as dated rows in the passport book.

vm tests: runner advance/abandon semantics via the queue-state seam.

* fix(career): stage restore survives a setViz throw; size-register row

CodeRabbit on #956: a setViz failure nulled the restore snapshot AFTER
the overrides were written, permanently borrowing the stage — snapshot
now captured before any write, write failures keep it intact. Also
registers career screen.js in docs/size-exemptions.md 'Planned, not
exempt' (1,516 lines; max-lines WARNS non-blocking — the split plan
needs Byron's sign-off).
