Greptile Summary

This PR bumps the minimum required Node.js version from 20.19.0 to 22.12.0, addressing issue #6054. Node 20 reached end-of-life in April 2026, making Node 22 (Active LTS) the appropriate new baseline.

• The change is a single-line update to the Node.MIN_VERSION constant in installer.py, which is already the sole source of truth — all version checks and error messages across js_runtimes.py and exec.py consume it via constants.Node.MIN_VERSION, so no other files need updating.
• The existing CI workflow (check_node_latest.yml) tests against node: \"node\" (latest), which will continue to cover compatibility going forward.

Confidence Score: 5/5

Safe to merge — a focused one-line constant bump with no ancillary files requiring updates.

The change touches a single centralized constant. All downstream version checks already reference this constant, there are no hardcoded version strings elsewhere that need to be kept in sync, and the CI pipeline tests against the latest Node release, so any runtime incompatibility would surface in CI before merge.

No files require special attention.
