v0.2.4

Reliability and control release. Improves hotkey handling, startup
readiness, microphone selection, cancellation, paste behavior, and
text-correction workflows. No migration steps — brew upgrade --cask parakey or the in-app Update now… button handles everything.

Dictation Reliability

• Hotkey handling — suppresses only the configured dictation hotkey,
  handles right-side modifier keys correctly, ignores F-key auto-repeat
  for recording transitions, and keeps the event-tap path responsive.
• Startup readiness — starts the audio engine before enabling
  dictation, blocks recording until required permissions are granted,
  and adds retry actions when speech model, audio input, or hotkey
  startup fails.
• Audio recovery — restores system audio if Parakey quits during a
  muted recording and refreshes audio input after microphone route
  changes.

Settings And Workflow

• Microphone selection — adds a microphone picker, remembers the
  selected device, falls back cleanly when it is unavailable, and hides
  CoreAudio's default aggregate pseudo-device from the explicit list.
• Recording control — adds Escape/menu cancellation for active
  recordings without paste, history, or completion sound.
• Paste behavior — lets you append a space, append a newline, or add
  no suffix after pasted dictation.
• Feedback sounds — adds a setting to turn start/completion sounds
  off while keeping dictation behavior unchanged.

Text Corrections And Support

• Recent transcript actions — clears in-memory recent transcripts
  and can seed a new correction from the latest transcript without
  logging transcript text.
• Diagnostics copy — copies a transcript-free support summary with
  app, permission, microphone, and setting metadata.
• Correction sharing cleanup — removes temporary correction-share
  files after the share flow finishes or is dismissed.

Privacy

• No telemetry, analytics, crash reporting, cloud transcription, new
  Parakey network call, or expanded entitlement was added.
