ci: Improved the issue of delayed pre-commit lint error detection, resulting in rework.

Lack of code quality verification during the commit phase necessitates rework when lint errors are discovered in CI.

Added Husky and lint-staged to automatically run lint only on targets that have changed during commit.
- Automatically fixable errors are fixed and committed, while unfixable errors are blocked.
- Added root-level dependency installation to just deps.
