Code Review

This pull request improves the prompts for generating pull request descriptions and commit messages by instructing the AI to ignore gitignored and irrelevant files. It also refactors the "Create PR" dialog to better handle long content by making the main area scrollable.

The prompt updates are a good improvement. I've suggested a small refinement in generate-pr-description.ts to combine the new rules for better consistency and conciseness, similar to the change made in defaults.ts.

The UI changes in the CreatePRDialog are well-implemented and correctly use flexbox properties to create a robust and scrollable layout.

Overall, these are solid improvements.

[gemini-code-assist]

For consistency with the changes in libs/prompts/src/defaults.ts, consider combining these two rules into a single, more concise instruction. This also improves prompt efficiency.

For example:

- Ignore changes to gitignored files (e.g., node_modules, dist, build, .env files, lock files, generated files, binary artifacts, coverage reports, cache directories). Focus only on meaningful source code changes that are tracked by git and relevant to reviewers.

In `@apps/ui/src/components/views/board-view/dialogs/create-pr-dialog.tsx`:
- Line 742: The DialogFooter's className uses the removed Tailwind v4 utility
"flex-shrink-0" which produces no styles; change that class to "shrink-0" in the
DialogFooter component (look for DialogFooter className="flex-shrink-0 pt-2
border-t") so the footer will not shrink unexpectedly under Tailwind v4.1.18 and
tailwind-merge@3.4.0.
