feat(framework): superpowers enforcement, typecheck hook, file-ownership rules

- Add PostToolUse typecheck hook (typecheck-hook.sh) that runs tsc --noEmit
  after TS/TSX edits for immediate type error feedback
- Add Superpowers Enforcement section to AGENTS.md requiring active use of
  skills, hooks, MCP tools, and plugins — not just passive availability
- Add self-evolution captures (framework-improvement, tooling-gap, friction)
- Add file-ownership/partitioning rules to ORCHESTRATOR.md preventing parallel
  worker file collisions
- Add settings audit to launch.ts that validates ~/.claude/settings.json has
  required hooks and plugins at mosaic claude launch time
- Document required Claude Code settings in RUNTIME.md
