ayurishchevandClaude Sonnet 5.5 0532baff09 Keep one address per validator; fix heartbeat handling and queue clear
A mass check on 2026-10-02 stalled 7 of 20 validators and sent 42
addresses to fail without a single check. A validator busy with slow
checks went silent, was marked unreachable, and its next heartbeat put it
back to idle while it still held the address; it was handed a second one,
whose association never ran (the in-flight guard was keyed by validator),
and both waited for their leases to expire.

- Heartbeat/re-register return an unreachable validator to assigned when
  it still holds an address, else idle.
- A validator is released only from the address it currently holds
  (ReleaseFIP, RequeueOrFail, MarkFIPOccupied, FreeValidator); an
  unreachable validator stays unreachable until its next heartbeat, so a
  dead validator is no longer handed a new address every lease period.
- ClaimNextQueued refuses a validator that still has an address; a
  ReconcileValidators pass on every tick repairs rows that disagree with
  the queue.
- Association guard is keyed by address, not validator.
- The agent sends heartbeats from their own goroutine.
- Clear queue / delete: detach only floating IPs of unfinished rows (done,
  failed and occupied rows kept their fip_id and made a clear issue >1000
  sequential cloud calls: 256 s), at most 8 in parallel; the operation no
  longer dies with the client connection (10 minute limit).

Includes the incident analysis and the plan under analysis/ and
docs/changes/, and rebuilt bin/control-api and bin/validator-agent.
