feat(face): integrate Idle Task Protocol v1.0 end-to-end

Watchface now syncs with the Nine Hazes idle task system via its own
pkjs client — the three-artifact architecture is operational.

Wire side:
- pkjs fetches GET /v1/queue on launch, applies clock offset, converts
  epoch-ms to seconds for AppMessage, resolves task name from the
  cached dictionary (refetch on version drift)
- GameSnapshot persisted at key 0x30 (protocol-specified); task name
  at 0x32 (face-local nicety)
- AppMessage inbox widened to 256 bytes to carry the full snapshot
  dictionary in a single logical message

Display side:
- Task strip renders two lines: countdown-to-completion + used/36 +
  task count, then task name with "(+)" pending-rewards cue
- Status states render distinctly: FROZEN / ABORTED(code) / LOCKED /
  No hero yet (EMPTY)
- serverDown sentinel key: oxblood "!" icon on failed check; absence
  on successful sync clears it; volatile — never persisted
- Countdown math is server-clock corrected (clock_off), computed
  locally from bound_sec — zero radio to stay fresh

Also:
- ES5-normalized pkjs for SDK webpack 1.15/acorn parser
- Replaced face_packet.{h,c} with snapshot.{h,c} (PACKET_KEY 101
  retired; old blob orphaned harmlessly)
- Mock Task API server seeded with 3-task queue (in-memory)

Verified: seeded queue renders "0:xx 16/36 seg 3 tasks / Gather (+)";
server kill → cached strip + offline icon, no error surface.
