Merge remote-tracking branch 'origin/master' into codex/status-bar-token-metrics

Conflict resolution notes:

- StatsLine: master redesigned the row into pipe-separated groups with LLM and
  tool wall times. Kept that design and swapped only the token accounting
  source, so counts and durations stay window-scoped while billing and context
  occupancy read the durable projections.
- Generated artifacts (cordis catalog, module graph, event producer/consumer,
  i18n pairing hashes) and web snapshots took master's side; they are
  regenerated and re-recorded after this merge.
- Web e2e goldens and details-panel/timeline assertions took master's side:
  that evolution is unrelated to this branch.
- ui-conversation package.json: kept master's devDependency ordering, re-adding
  only the token-meter entry this branch needs.
