v0.2.3

Backchannel v0.2.3

This patch release stabilizes live audio startup and speaker attribution for
calls with one local microphone user and remote participants on system audio.

Highlights

• Prevent duplicate capture pipelines and call segments during rapid Start,
  Resume, End, or delayed browser permission prompts.
• Bind split-track microphone speech to the sole configured local user without
  consuming remote speaker slots; system-audio participants retain normal
  diarization.
• Preserve the capture topology for queued, reconnect-flushed, and final audio,
  and return to normal mic-only diarization when system sharing ends.
