ci: per-package CI matrix with coverage enforcement and Codecov

- Rewrite CI workflow with dorny/paths-filter to detect changed packages
- Run lint/typecheck/build/test:cov as separate jobs per affected package
- Lower coverage thresholds to current floors to prevent regression
- Add per-package coverageThreshold overrides in each jest.config.ts
- Have all packages extend baseConfig from jest.preset.ts
- Add codecov.yml with 80% patch target for new code
- Add deps:graph script to root package.json
