v0.3.27

Added

• Thinking block count tracking (src/usage/extract.ts, src/usage/types.ts,
  src/usage/ddl.ts, src/db.ts): counts thinking/reasoning content blocks
  observed in both Anthropic and OpenAI streams. Bridges the gap when upstream
  omits thinking_tokens / reasoning_tokens but emits thinking content —
  the dashboard now shows "N req w/ think (unmeasured)" instead of hiding
  thinking activity entirely.

  • Anthropic: counts content_block_start events with type: "thinking".
  • OpenAI: counts chunks with delta.reasoning_content (streaming) or
    non-empty message.reasoning_content (non-streaming).
  • New thinking_block_count column in captures (DDL migration).
  • Aggregated as requests_with_thinking in performance stats query.

• Dashboard: unmeasured-thinking indicator (dashboard/src/components/performance-meter.tsx,
  dashboard/src/types.ts): the "Total Out" StatTile now shows "N req w/
  think (unmeasured)" when thinking tokens are absent but requests had
  thinking blocks, instead of always showing "0 think". Hides the sub-line
  entirely when both tokens and request count are zero.

Fixed

• Vitest teardown race in dashboard tests (dashboard/vitest.config.ts):
  the default forked worker pool raced console.log RPC delivery against
  teardown, producing an EnvironmentTeardownError ("Closing rpc while
  'onUserConsoleLog' was pending") that exited non-zero despite all tests
  passing — failing CI. Set fileParallelism: false + maxWorkers: 1 to
  eliminate the race.
