Claude Code can report its pane command as "node", "claude", or a version number like "2.0.76". Previously only "node" was detected, causing healthy sessions to be incorrectly identified as zombies and killed during daemon heartbeat recovery. This fix detects all three patterns to prevent witness sessions from being killed every 3 minutes. Based on michaellady's work in PR #174.
