fix: complete TypeScript strict mode sync with main

- Updated tsconfig.all.json to use main's strict TypeScript configuration
- Fixed unnecessary type assertions in agent-work-verifier.ts and fs-extra-safe.ts
- Resolved 305 ESLint errors by aligning TypeScript strictness with ESLint rules
- All tests pass with 84.08% branch coverage (above 78% threshold)
- CI pipeline now passes completely

This completes the clean sync baseline between main and test branches.
