build: add pre-commit hooks with simple-git-hooks and lint-staged

Replace redundant root-level script aliases (dev, build, test:unit, lint,
etc.) that merely wrapped `pnpm -r run <task>`. Each sub-package already
defines its own scripts, so the aliases added no value.

- Add simple-git-hooks + lint-staged for pre-commit quality gates
  (oxlint/oxfmt on staged files, then unit tests across all packages)
- Keep only `prepare` script to auto-install hooks on `pnpm install`
- Update CI workflow to call `pnpm -r run` directly
