feat: Phase 1 — Arc Reactor Core Daemon

- Python asyncio daemon (/opt/jarvis-arc/reactor.py) running on 127.0.0.1:7474
- systemd service (jarvis-arc) auto-starts with MySQL dependency
- arc_jobs + arc_status MySQL tables for async job queue
- api/endpoints/arc.php: PHP bridge to daemon (status, job_create, job_get, jobs, purge)
- api.php: added arc route
- index.html: ARC REACTOR status indicator in bottom bar with live polling
- admin/index.php: ARC REACTOR nav section + full job management panel
- Built-in job handlers: ping, echo, shell (whitelist-gated)
- Foundation for Phase 2 (Intel Protocol) and beyond
