fix(test): reduce benchmark execution time from 10+ minutes to <10 seconds

Major performance improvements:
- Remove incorrect build tags that prevented container usage
- Add Docker detection to skip integration benchmarks gracefully in CI
- Fix BenchmarkWorkerPool deadlock with concurrent draining
- Create optimized Makefile targets for different scenarios:
  - test-benchmark-ci: 60s timeout, 100ms benchtime (CI default)
  - test-benchmark-fast: 30s timeout, 10ms benchtime (quick dev)
  - test-benchmark-full: 300s timeout, full runs (local with Docker)
- Update CI workflow to use fast benchmark target with 2-minute timeout

Results:
- CI benchmarks: ~10 seconds (was timing out at 10 minutes)
- Fast benchmarks: ~2 seconds (for rapid development feedback)
- No more NaN results or hanging tests
- Clean separation between unit and integration benchmarks

Fixes the root cause: build tag confusion where files marked !integration
were trying to use integration test infrastructure (SetupTestContainer).
