Module lifecycle 

Background lifecycle tasks for the lock registry.

• start_heartbeat_loop: spawns a tokio task that scans for stale locks every interval and emits lock:released { reason: ttl } for each.

OCP contract

The heartbeat loop is generic over EventEmitter, so any emitter (real Tauri AppHandle or MockChannel) can be substituted without changing this module.

Functions

current_unix_secs

Return current Unix timestamp in seconds.

start_heartbeat_loop

Spawn a tokio task that periodically scans for stale locks and releases them.

start_heartbeat_loop_handle

Convenience wrapper that accepts a LockRegistryHandle instead of a bare Arc<LockRegistry>.
