Subject: [PATCH] fix: add polling timeouts and safe fallback in recovery
 script (#644)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add max-iterations guard (60 polls × 5s = 5 min) to both cooldown
  polling loops with explicit error on timeout
- Use LAST_RECENTER (already validated) as fallback instead of "0" for
  post-seed-buy lastRecenterTime read, preventing silent cooldown skip
  on transient RPC failure
