* fix(runtime): bump minimum Node.js version to 22.12.0
Aligns the runtime guard with the declared package.json engines requirement.
The Matrix plugin (and potentially others) requires Node >= 22.12.0,
but the runtime guard previously allowed 22.0.0+. This caused confusing
errors like 'Cannot find module @vector-im/matrix-bot-sdk' when the real
issue was an unsupported Node version.
- Update MIN_NODE from 22.0.0 to 22.12.0
- Update error message to reflect the correct version
- Update tests to use 22.12.0 as the minimum valid version
Fixes#5292
* fix: update test versions to match MIN_NODE=22.12.0
