v0.2.20

What's Changed

• Rapid dictation stability: Parakey now keeps the microphone engine warm
  briefly between rapid dictations instead of tearing CoreAudio down and
  rebuilding it after every release. This avoids a reproducible freeze after
  several quick uses while still closing the input session after the user
  pauses.
• Audio route handling: Configuration-change notifications caused by
  Parakey's own audio-engine start/stop cycle are ignored, so they no longer
  trigger redundant deferred restarts during normal dictation.
• Filler-word cleanup: Removing a sentence-start filler inside a longer
  transcript now restores the capitalization of the next word. For example,
  This is the first sentence. Um this is the second sentence. now becomes
  This is the first sentence. This is the second sentence.

Validation

• Ran the full in-binary self-test suite.
• Ran a signed dev-app stress check with 15 rapid event-tap dictation cycles
  and confirmed the app stayed responsive, reused the warm input engine for
  the burst, then closed it after the idle delay.
