Bring in the Python 3.14 runtime pins and wake-engine changes while preserving the staged stable-release gate and review fixes. The merge has no conflicts. Targeted tests on the existing Python 3.11 dev environment passed: 130 passed, 8 skipped. The lock check passed with Python 3.14.7. Workflow lint and shell syntax checks also passed. Full Python 3.14 runtime and native release acceptance remain for CI.
