Addresses review on #5168:
- Generational aliasing (blocking): setupConnection()/onReconnectTimeout()
rebuild wp_core_/om_/pending_plugins_ in place on the same self, but the
async load/activate callbacks carried no generation, and isModuleAlive()
only proves self still exists. If PipeWire dropped again while a previous
connection's async chain was still in flight, a stale completion would run
against the rebuilt connection (a stray --pending_plugins_, an out-of-order
install_object_manager), re-creating #2882's stale/blank state. Each async
call now carries an AsyncCall{self, generation}; connection_generation_ is
bumped in setupConnection(), and every callback drops out when its
generation no longer matches (checked after isModuleAlive short-circuits).
- Duplicate scroll handlers: onMixerApiLoaded re-runs on every reconnect and
connected a new scroll handler each time (dead but accumulating). Moved the
one-time wiring to the constructor; handleScroll no-ops while mixer_api_ is
null, so wiring it before the first connect is safe.
