refactor: replace lock unwraps with poison-aware helpers

Browse Source 
Add SoulseekRs::LockPoisoned variant and a small RwLockExt/MutexExt
helper module exposing read_safe/write_safe/lock_safe that map
PoisonError to that variant. Walk every non-test lock acquisition
across client, peer/server actors, peer registry, listener and the
thread pool: propagate via ? where the function returns Result, log
and degrade to a sensible default (return early, false, None, empty)
where it does not. Client::connect now returns Result so the CLI can
surface the failure instead of panicking.
