fix(phase5): align configs and add agent tests

- Add PLR0912, PLC0415 to ruff ignore list for complex orchestrator logic
- Disable warn_unused_ignores in mypy (vendored lib needs type: ignore)
- Fix single ChatMessage input handling in SearchAgent/JudgeAgent
- Add comprehensive unit tests for SearchAgent and JudgeAgent wrappers
- All 38 tests pass, lint and mypy clean, pre-commit aligned
