fix: refresh tasks snapshot immediately after IPC task mutations

Previously, current_tasks.json was only written at container-start time,
so tasks created (or paused/cancelled/updated) during a session were
invisible to list_tasks until the next invocation.

Add an onTasksChanged callback to IpcDeps, called after every successful
mutation in processTaskIpc (schedule_task, pause_task, resume_task,
cancel_task, update_task). index.ts wires it up to write fresh snapshots
for all registered groups immediately, keeping no new coupling between
ipc.ts and the container layer.
