feat: Remove gt spawn completely - gt sling is THE command (gt-1py3y)
Fully remove gt spawn from the codebase: - Delete spawn.go, create polecat_spawn.go with just sling helpers - Remove all gt spawn references from docs and CLAUDE.md - Update code comments to reference gt sling gt sling now handles ALL work dispatch: - Existing agents: gt sling <bead> mayor/crew/witness - Auto-spawn: gt sling <bead> <rig> - No-tmux: gt sling <bead> <rig> --naked - With args: gt sling <bead> --args "..." 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
