v0.3.5

Presspeech 0.3.5

This patch lets longer macOS dictations finish naturally while preserving the
automatic recording safety cutoff.

Configurable recording length

• Settings → Behavior → Maximum Recording Length now offers 1, 2, 5, and 10
  minute limits. The existing two-minute limit remains the default.
• Reaching the selected limit still stops, transcribes, and pastes the captured
  dictation, so a forgotten toggle cannot record indefinitely.
• Hand-written max_recording_seconds defaults values are constrained to 30
  seconds through 10 minutes to keep in-memory audio bounded.

There is no speech-model migration in this release. Audio and transcripts
remain on the Mac, and transcript text never enters the diagnostic log.
