Preparation for auto-restart: extract bip157 node build logic into a reusable helper method, add chain_state() from wallet checkpoint to avoid genesis re-sync, and thread Arc<Wallet> through start(). AI: claude
When node.run() exits (e.g. NoReachablePeers from kyoto lightningdevkit#558), the background task rebuilds the node, swaps the requester, and respawns channel processing tasks, up to MAX_RESTART_RETRIES (5) attempts with doubling backoff starting at 500ms. - Change cbf_runtime_status from Mutex<> to Arc<Mutex<>> so it can be shared with the async restart loop - Extract build_cbf_node_static() that takes explicit params instead of &self, enabling calls from 'static async blocks - Move all task spawning (info/warn/event + node.run) into a single restart loop inside spawn_background_task AI: claude
requester() now checks is_running() to give callers an immediate failure signal instead of waiting for SendError to propagate through the channel.
Extract cleanup_scan_state() helper and call it on error paths in run_filter_scan() to prevent stale watched_scripts, matched_block_hashes, and filter_skip_height from leaking between scans.
Wrap individual get_block() calls in tokio::time::timeout using the existing per_request_timeout_secs config. Previously only the overall sync had a timeout; individual block fetches could hang indefinitely (kyoto lightningdevkit#556).
