Add standardized CI lint workflow and enhance pre-commit hook

[tarrencev]

Summary

• Add comprehensive GitHub Actions workflow for linting and code quality checks
• Enhanced .githooks/pre-commit with better output formatting, error handling, and comprehensive file processing
• Workflow includes Rust formatting (cargo +nightly fmt) and strict linting (clippy with comprehensive rules)
• Ensures consistent code quality across the project by automating existing linting standards

Test plan

• Created .github/workflows/lint.yml with comprehensive linting steps
• Enhanced .githooks/pre-commit with improved formatting and error handling
• Workflow uses nightly Rust toolchain matching project conventions
• Includes strict clippy rules: warnings, future-incompatible, nonstandard-style, rust-2018-idioms, unused
• Runs on push/PR to main and develop branches
• Matches and enhances existing script-based linting approach

✅ Completed PR Review: Add standardized CI lint workflow and enhance pre-commit hook

Todo List:

• Create pending PR review
• Get PR diff information
• Review GitHub Actions workflow (.github/workflows/lint.yml)
• Review pre-commit hook (.githooks/pre-commit)
• Submit comprehensive review

Summary

I've completed a thorough code review of this PR. The implementation is excellent overall with just one minor issue:

Key Findings:

• ✅ GitHub Actions workflow properly configured with nightly Rust toolchain
• ✅ Pre-commit hook significantly improved with better UX and error handling
• ✅ Comprehensive clippy rules match project standards
• ✅ Smart file processing and good separation of concerns
• ⚠️ Minor: Missing trailing newline in lint.yml

Recommendation: This is a high-quality enhancement that will improve development workflow. Ready to merge after addressing the minor newline issue.

The detailed review has been submitted to the PR with comprehensive analysis of code quality, security, performance, and best practices.

To fix the problem, add a permissions block to the workflow to explicitly set the minimum required permissions for the GITHUB_TOKEN. Since the workflow only needs to check out code and does not perform any actions that require write access (such as creating issues, pushing code, or modifying pull requests), the minimal permission required is contents: read. This can be set at the workflow level (applies to all jobs) or at the job level (applies only to the lint job). The best practice is to set it at the workflow level unless a job requires different permissions. Add the following block after the name field and before the on field:

permissions:
  contents: read

No additional imports, methods, or definitions are needed.

Code Review Summary

This PR successfully adds a comprehensive CI linting workflow and enhances the pre-commit hook. The implementation is well-thought-out and follows good practices.

✅ Strengths

GitHub Actions Workflow:

• Uses appropriate GitHub Actions with correct versions
• Properly configured nightly Rust toolchain matching project conventions
• Comprehensive clippy rules covering warnings, future-incompatible, nonstandard-style, rust-2018-idioms, and unused
• Includes build and test validation steps
• Appropriate trigger conditions for main and develop branches

Pre-commit Hook Enhancement:

• Excellent user experience improvements with colored output and clear messaging
• Smart file filtering to only process staged Rust files
• Proper error handling with meaningful exit codes
• Good separation of formatting vs linting concerns
• Informative feedback when files are auto-formatted

🔧 Minor Issues

1. Missing newline: The lint.yml file is missing a trailing newline (line 33). This follows POSIX standards and avoids potential tool issues.

🏆 Code Quality Assessment

• Best Practices: ✅ Excellent
• Security: ✅ No concerns identified
• Performance: ✅ Efficient staged file processing
• Test Coverage: ✅ Workflow includes test execution
• Maintainability: ✅ Clear, well-documented code

The implementation aligns perfectly with the project's existing linting standards while providing much better automation and developer feedback. This will significantly improve code quality consistency across the project.

Recommendation: Approve with the minor newline fix.

Bug: Rust Pre-commit Hook Fails on Spaces

The pre-commit hook incorrectly formats Rust files and fails to handle filenames with spaces.

1. Incorrect cargo fmt invocation: The cargo +nightly fmt command is passed file arguments directly, which cargo fmt does not accept, and includes an invalid --edition 2021 flag. This will cause the formatting step to fail or behave unexpectedly.
2. Filenames with spaces: The script fails to properly handle filenames containing spaces. Both the xargs command used for formatting and the subsequent loop checking for modifications will split such filenames on whitespace, leading to errors or processing of incorrect file paths.
