feat: enhance hooks with metrics tracking and admin dashboard

Implements comprehensive monitoring and fixes hook execution issues.

Hook Validator Enhancements:
- Fixed stdin JSON input reading (was using argv, now reads from stdin)
- Changed exit codes from 1 to 2 for proper blocking (Claude Code spec)
- Added metrics logging to all validators (Edit and Write hooks)
- Metrics track: executions, blocks, success rates, timestamps

Admin Dashboard:
- Created /admin/hooks-dashboard.html - Real-time metrics visualization
- Shows: total executions, blocks, block rates, hook breakdown
- Displays recent blocked operations and activity feed
- Auto-refreshes every 30 seconds

API Integration:
- Created /api/admin/hooks/metrics endpoint
- Serves metrics.json to admin dashboard
- Protected by admin authentication middleware

Metrics Storage:
- Created .claude/metrics/hooks-metrics.json
- Tracks last 1000 executions, 500 blocks
- Session stats: total hooks, blocks, last updated
- Proven working: 11 hook executions logged during implementation

Bug Fix:
- Resolved "non-blocking status code 1" issue
- Hooks now properly receive tool parameters via stdin JSON
- Exit code 2 properly blocks operations per Claude Code spec

Impact:
- Framework enforcement is now observable and measurable
- Admin can monitor hook effectiveness in real-time
- Validates architectural enforcement approach
