Developer QOL

[kingbuzzman]

• This update addresses two common pain points when developing on github.com's browser editor:
  1. Delayed CI Testing: Small changes often accumulate, causing the CI to wait for all previous commits before testing your current commit. This delay can be inefficient. Suggestion: Cancel previous CI runs when pushing new commits to speed up the feedback loop.
  2. Lack of Fix Suggestions for ruff Issues: When ruff flags an issue, it highlights the problematic code block but doesn't suggest how to fix it. By adding the --diff option, you can see the differences and get guidance on correcting the issue.

All this came about while working on #1170
