A. F. DudleyandClaude Opus 4.6 3bf87a2e9b feat: snapshot leapfrog — auto-recovery when validator falls behind

Entrypoint changes:
- Always require full + incremental before starting (retry until found)
- Check incremental freshness against convergence threshold (500 slots)
- Gap monitor thread: if validator falls >5000 slots behind for 3
  consecutive checks, graceful stop + restart with fresh incremental
- cmd_serve is now a loop: download → run → monitor → leapfrog → repeat
- --no-snapshot-fetch moved to common args (both RPC and validator modes)
- --maximum-full-snapshots-to-retain default 1 (validator deletes
  downloaded full after generating its own)
- SNAPSHOT_MAX_AGE_SLOTS default 100000 (one full snapshot generation)

snapshot_download.py refactoring:
- Extract _discover_and_benchmark() and _rolling_incremental_download()
  as shared helpers
- Restore download_incremental_for_slot() using shared helpers (downloads
  only an incremental for an existing full snapshot)
- download_best_snapshot() uses shared helpers, downloads full then
  incremental as separate operations

The leapfrog cycle: validator generates full snapshots at standard 100k
block height intervals (same slots as the rest of the network). When the
gap monitor triggers, the entrypoint loops back to maybe_download_snapshot
which finds the validator's local full, downloads a fresh network
incremental (generated every ~40s, converges within the ~11hr full
generation window), and restarts.
