ci: run tests on Node 24.10.0 only

Changes:
- Update default node-versions from [20, 22, 24] to ["24.10.0"]
- Update e2e test matrix to use Node 24.10.0 only
- Update commented sharded test matrix for consistency

This reduces CI matrix combinations and focuses testing on the target
Node.js version for Socket CLI.
