feat: Global hooks approval modal with plan/question/permission modes

- Add PermissionRequest and Stop approval hooks to local Claude config
- Unify PermissionApproval into multi-mode card (permission, plan, question)
- Support allowAlways, deny-with-reason, and AskUserQuestion answering
- Add cross-process broadcast fallback (HTTP to sync server)
- Fix approval scripts to default to .claude/debug/ for local agent
