feat(orchestrator): emphasize project-level lsp_diagnostics and QA verification

- Add mandatory PROJECT-LEVEL code checks (lsp_diagnostics at src/ or . level)
- Strengthen verification duties with explicit QA checklist
- Add 'SUBAGENTS LIE - VERIFY EVERYTHING' reminders throughout
- Emphasize that only orchestrator sees full picture of cross-file impacts

+- Subagents may "fix" one file but break dependencies
