feat: N+1 detection, auto-instrumentation, diff, AI explain, and new exports#9
Merged
Conversation
Set FORCE_JAVASCRIPT_ACTIONS_TO_NODE24=true at workflow level for both ci.yml and release.yml to silence the actions/checkout@v4 + actions/setup-node@v4 Node 20 deprecation warning. Rename the 'Test with coverage' step to 'Test with coverage gate (>=90%)' to make the threshold explicit. The threshold itself is unchanged — it is enforced via npm run test:coverage which is c8 --check-coverage --lines 90 --functions 90 --branches 90 --statements 90.
