fix: add typecheck to CI, fix code-quality paths, align ESLint versions, document workspace exclusions

- CI workflow: add pnpm typecheck step
- code-quality workflow: fix src/ → packages/ references, use typecheck instead of build
- package.json: align @typescript-eslint/parser ^6.21.0 → ^7.18.0 with plugin
- pnpm-workspace.yaml: add comment explaining core/server exclusion
