feat(cli): figma import telemetry — subcommand labels, typed error codes, figma_import event (#1979)

Closes the observability gaps on the figma integration:
- withFigmaErrors takes a command label (figma:asset|tokens|component) and
  reports the failure inline before its process.exit — the top-level
  trackCommandFailures wrapper never sees self-exiting commands, so typed
  codes (NO_TOKEN, BAD_TOKEN, FORBIDDEN, RATE_LIMITED) were invisible.
  FigmaClientError codes surface as the error name for dashboarding the
  first-run funnel (NO_TOKEN -> later success = onboarding conversion).
- new figma_import event per import: phase, duration, reused (dedup
  effectiveness), tokens variables-vs-styles mode + entry count
  (Enterprise gating rate), unresolved-binding + rasterized-node counts
  (fidelity degradation). No fileKeys, node ids, names, or descriptions.
- /figma skill fires the events beacon (figma-motion / figma-shaders /
  figma-storyboard) for the MCP phases that never touch the CLI.
