fix: add libudev-dev to servo Dockerfile + mark 92 DaytonaError runs invalid

- Add libudev-dev to servo-scrollend-event-feat-001 Dockerfile and Dockerfile.sg_only
  (needed by libudev-sys Rust crate for pkg-config libudev.pc lookup)
- Mark 80 DaytonaError trial dirs with __invalid_daytona_error marker files
  (DaytonaErrors have None tokens but _has_agent_output() returned True,
   causing them to supersede good results in MANIFEST dedup by timestamp)
- Mark 12 RewardFileNotFoundError/AgentSetupTimeoutError MCP runs as invalid
- Regenerate MANIFEST: ccb_feature 0 errored (was 10), ccb_refactor 0 errored
- Add docs/official_results/traces/ to .gitignore (OAuth tokens in agent traces)
- Include retrieval_events and docs/official_results updates from prior sessions
