fix: configure husky and lint-staged for pnpm monorepo (#384)

# Improve Developer Experience with Husky and lint-staged for pnpm
Monorepo

## Summary
This PR enhances the developer experience by configuring Husky and
lint-staged to work properly with our pnpm monorepo structure. It
centralizes Git hooks at the root level and ensures consistent code
quality across the project.

## Changes
- Centralized Husky and lint-staged configuration at the monorepo root
- Added pre-commit hook that runs lint-staged to enforce code quality
- Configured lint-staged to:
  - Format JSON, MD, and YAML files with Prettier
  - Lint and typecheck TypeScript files before commits
- Fixed release script in codex-cli package.json (changed "pmpm" to "npm
publish")
- Removed duplicate Husky and lint-staged configurations from codex-cli
package.json

## Benefits
- **Consistent Code Quality**: Ensures all committed code meets project
standards
- **Automated Formatting**: Automatically formats code during commits
- **Early Error Detection**: Catches type errors and lint issues before
they're committed
- **Centralized Configuration**: Easier to maintain and update in one
place
- **Improved Collaboration**: Ensures consistent code style across the
team

## Future Improvements
We could further enhance this setup by
**Commit Message Validation**: Add commitlint to enforce conventional
commit messages
