fix: add missing Makefile targets and test timeout

- Add docker target (runs docker build .)
- Add hooks target (installs pre-commit hook running make check)
- Add 30-second timeout to test target (-timeout 30s)
- Update README to document all Makefile targets
- Run make fmt to fix JS formatting (prettier)
