The published runtime requirement and CI allowed Node 20 and pre-fix Node releases. Require patched Node 22.23.4, 24.22.1, or 26.12.1 and run CI against the fixed supported branches. Local development selects 24.22.1. This addresses the Brotli decoder memory corruption plus the TLS/HTTP/DNS and CA updates in the official October Node advisory.

Validation: existing offline test suite passed on a separately downloaded Node 24.22.1, verified against the official SHASUMS256.txt. CI tests the configured fixed branches. No live API spend.

This changes repository requirements and CI; it does not update already installed npm packages or running services. Consumers must update their Node executable and restart applications. Rollback: revert this commit; retain a patched Node runtime.
