Conversation
🎯 What: Refactored the `main` function in `src/main.py` by extracting command handling logic into individual helper functions and using a dispatch dictionary (`COMMAND_HANDLERS`). 💡 Why: The `main` function previously contained a long, complex chain of `if args.command == ...:` statements, resulting in high cyclomatic complexity. This refactoring greatly improves maintainability, readability, and testability by separating concerns and reducing the cognitive load required to understand the entry point. It also optimizes performance by lazily building `manifest` only for commands that need it. ✅ Verification: Ran `ruff format` and `ruff check` to ensure clean code. Executed `PYTHONPATH=. python3 -m unittest discover tests` to confirm no existing functionality was broken. ✨ Result: The `main` function is now clean and concise, and the code health issue regarding cyclomatic complexity is fully resolved.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs.

Pull request overview
Refactors the CLI entrypoint to reduce cyclomatic complexity by moving per-command logic into dedicated handler functions and dispatching via a command→handler map; additionally applies broad formatting/quoting normalization across Python (and a couple of scripts).
Changes:
- Extracted
src/main.pycommand handling into helper functions and aCOMMAND_HANDLERSdispatch dictionary. - Normalized string quoting / formatting across many modules and tests (ruff-driven).
- Minor readability formatting in a few utility scripts (Rust harness script, doc check script, patch helper).
