Subject: [PATCH] Fix pre-commit OOM: batch cppcheck, cap Node heap, fail-fast

- cppcheck: process files one-at-a-time (xargs -n 1) + --check-level=normal
- eslint: cap Node.js heap to 512MB via NODE_OPTIONS
- Set fail_fast: true to avoid stacking memory-heavy hooks
- Remove ulimit -v (ineffective with Linux memory overcommit)
