feat(publish): tell the user how many relays accepted their video

Publishing showed a flat "Video shared successfully!" even when most (or all)
relays rejected the event, so users couldn't tell a partial/failed publish from
a clean one. Now publishVideo captures the per-relay accept/reject summary and
stashes a compact {accepted,total} tally on the returned event via a
non-enumerable key (never serialized, never sent to relays). app.js reads it
back and reports the real outcome:
  - all relays accepted  -> "Video published to N relays!"
  - some rejected        -> warning "Video published to N of M relays …"
  - none accepted        -> error (defensive; this path normally throws first)
Falls back to the generic message when no tally is available.

Tests (describePublishOutcome + attach/readRelayPublishSummary): success/partial/
zero/singular/missing-tally messaging, and that the tally round-trips while
staying out of JSON serialization. Mutation-verified — flipping partial→success
and the summary key to enumerable both fail the suite.

Build + full lint green.
