fix(lefthook): replace hanging doctor prepush with direct test command

- Replace `doctor check --pre-push` (invalid syntax) with `bun run test`
- The doctor prepush command was hanging indefinitely during git push
- Direct test command is more transparent and works reliably
- Pre-push hook now completes in ~2 seconds instead of timing out

Resolves pre-push hook hang that required LEFTHOOK=0 to bypass.
