The peer runtime used to spawn each long-running service inline inside
run_peer. That made the startup path harder to scan because service names,
clone setup, and task error handling were interleaved with the command loop.
Move the task wrappers into a startup module and leave run_peer as the
lifecycle overview: create shared context, start services, handle commands,
then send shutdown goodbyes. The spawned services and their error handling are
unchanged; only the ownership plumbing moved into named helpers.

LanSpreadState now owns its empty initialization through Default. This keeps
the root runtime state construction in one place instead of building each
Arc<RwLock<_>> value inline before registering it with Tauri.
The setup hook now retrieves peer_game_db from the managed state and clones the
Arc before spawning async peer initialization. That preserves the existing
lifetime boundary while removing the separate outer peer_game_db binding.
There is no user-visible behavior change. The peer database, game list,
download tracking, games folder, and peer control channel still start empty and
are populated through the same setup and command paths.
