refactor(ci): streamline GitHub Actions workflows and fix pre-commit integration

- Remove redundant workflows (lint.yml, tests.yml, branch-specific CI/CD)
- Add unified ci.yml workflow for all branches with pre-commit, tests, and wheel size checks
- Add pre-commit-auto-fix.yml to automatically fix formatting issues on PRs
- Update wheel_size.yml to use Python script and latest action versions
- Update publish-pypi.yml to use latest action versions
- Fix wheel_size.yml to target 'dev' instead of 'develop' branch
- Add benchmark_env/ and notes/ to .gitignore
- Install pre-commit hooks locally to prevent GitHub failures

This eliminates workflow redundancy and provides better developer experience
with automatic pre-commit issue resolution.
