Without a bound, the loop runs forever if sources never serve an
incremental close enough to head (e.g. full snapshot base slot is
too old). After 30 minutes, proceed with the best incremental
available or none.

After the full snapshot downloads, continuously re-probe all fast sources
for newer incrementals until the best available is within convergence_slots
(default 500) of head. Each iteration finds the highest-slot incremental
matching our full snapshot's base slot, downloads it (replacing any previous),
and checks the gap to mainnet head.
- Extract probe_incremental() from inline re-probe code
- Add convergence_slots param to download_best_snapshot() (default 500)
- Add --convergence-slots CLI arg
- Pass SNAPSHOT_CONVERGENCE_SLOTS env var from entrypoint.py

The container entrypoint (entrypoint.py) handles snapshot download
internally via aria2c. Ansible no longer needs to scale-to-0, download,
scale-to-1 — it just deploys and lets the container manage startup.
- biscayne-redeploy.yml: remove snapshot download section, simplify to
teardown → wipe → deploy → verify
- biscayne-sync-tools.yml: new playbook to sync laconic-so and
agave-stack repos on biscayne, with separate branch controls
- snapshot_download.py: re-probe for fresh incremental after full
snapshot download completes (old incremental is stale by then)
- Switch laconic_so_branch to fix/kind-mount-propagation (has
hostNetwork translation code)
