Create Beads Orchestration

Each task gets its own worktree at `.worktrees/bd-{BEAD_ID}/`, tracked by the beads CLI. The setup runs a discovery agent that scans your stack and auto-generates supervisors, installs git hooks for code review gates, and optionally wires up the Kanban UI for visual tracking. You'll want this if you're tired of MCP overhead but still need agent delegation with real task isolation. The epic workflow handles cross-domain features by creating parent-child task hierarchies with explicit dependencies. Requires a Claude Code restart mid-setup to load the hooks, which is annoying but necessary.
