## Summary
Added Claude Code hooks to prevent common development mistakes when
working on the Bun codebase.
## Changes
- Created `.claude/hooks/pre-bash-zig-build.js` - A pre-bash hook that
validates commands
- Created `.claude/settings.json` - Hook configuration
## Prevented Mistakes
1. **Running `zig build obj` directly** → Redirects to use `bun bd`
2. **Using `bun test` in development** → Must use `bun bd test` (or set
`USE_SYSTEM_BUN=1`)
3. **Combining snapshot updates with test filters** → Prevents
`-u`/`--update-snapshots` with `-t`/`--test-name-pattern`
4. **Running `bun bd` with timeout** → Build needs time to complete
without timeout
5. **Running `bun bd test` from repo root** → Must specify a test file
path to avoid running all tests
## Test plan
- [x] Tested all validation rules with various command combinations
- [x] Verified USE_SYSTEM_BUN=1 bypass works
- [x] Verified file path detection works correctly
