bun install          # also installs the lefthook pre-push hook
bun test             # fast unit tests (test/)
bun run test:e2e     # integration tests against a throwaway git repo (e2e/)
bun run lint         # oxlint
bun run fmt          # oxfmt --write
bun run typecheck    # tsc --noEmit
bun run build        # -> out/extension.js

git push runs lint, fmt:check, typecheck, and test:e2e via lefthook (pre-push).
