feat: graceful shutdown, ZFS upgrade, storage migration, sync-tools build
- entrypoint.py: Python stays PID 1, traps SIGTERM, requests graceful exit
via admin RPC (agave-validator exit --force) before falling back to signals
- snapshot_download.py: fix break-on-failure bug in incremental download loop
(continue + re-probe instead of giving up)
- biscayne-upgrade-zfs.yml: upgrade ZFS 2.2.2 → 2.2.9 via arter97/zfs-lts
PPA to fix io_uring deadlock at kernel module level
- biscayne-migrate-storage.yml: one-time migration from zvol/XFS to ZFS
dataset (zvol workaround no longer needed with graceful shutdown + ZFS fix)
- biscayne-stop.yml: patch terminationGracePeriodSeconds to 300 before
scaling to 0, updated docs for admin RPC shutdown
- biscayne-sync-tools.yml: fix SSH agent forwarding (vars: ansible_become),
add --tags build-container support, add set -e to shell blocks
- biscayne-recover.yml: updated for graceful shutdown awareness
- check-status.py: add --pane flag for tmux, clean redraw in watch mode
- CLAUDE.md: update docs for ZFS dataset storage, graceful shutdown
