Libraries v0.40.40 optimizes core and excel-import with performance improvements; tightens CI/release gates for stability. Runtime packages v0.40.36 ships concurrently.

Why it matters: Standard maintenance release. Core and excel-import performance optimizations present; no breaking changes or security concerns. Test excel-import in dev if performance-critical; no migration needed.
