v2.0.0 - Remove beads integration

Breaking Changes

Beads task tracking has been removed from the kas workflow. The superpowers plugin (official Claude Code marketplace) now handles brainstorming, subagent spawning, and initial reviews.

Removed

• agents/task-splitter.md - No longer needed
• commands/next.md - Beads issue finder
• hooks/hooks.json - Beads daemon startup
• hooks/scripts/ensure-daemon.sh - Daemon script

Changed

• Simplified planning workflow: plan-reviewer → ExitPlanMode (no task-splitter step)
• Streamlined /kas:setup to check only gh/git prerequisites
• Updated all commands to remove beads references
• Added superpowers plugin as a prerequisite

Migration Guide

1. Install the superpowers plugin from the official marketplace
2. Remove .beads/ directory from your projects if no longer needed
3. Update any scripts or workflows that reference bd commands
