perf: Optimize PipeWire communication with single background thread actor

Replaces the previous approach of spawning new PipeWire main loops and
awaiting a 100ms timeout for every `get_all_devices` call. Instead,
this introduces a `PipeWireManager` which maintains a single, persistent
background thread with a PipeWire main loop and registry listener. The
actor caches `AudioDevice`s and `Port`s continuously in a `HashMap`,
providing instantaneous responses to device queries via a channel.

This architectural change replaces `Sender<Terminate>` with a simple
`PwTerminator` drop-guard to manage the lifetimes of PipeWire objects
(virtual mic and links) via `PwCommand::DestroyObject` without creating
additional OS threads or PipeWire contexts.
