SpotAI v1.3.3

🐛 Bug Fixes

• 🎙️ Dictation Actually Works: Three fixes make transcription reliable end-to-end. The recorded WAV header now carries the real device sample rate (no more hardcoded 16 kHz that made Whisper hear desktop mics at 44.1/48 kHz ~3× slower and fail), the selected voice engine + microphone are synced to the backend at startup (no more reverting to the broken native engine after a restart), and silent captures show an honest "No speech detected" instead of injecting a [BLANK_AUDIO] token.

🧪 Tests

• 📼 WAV Header Tests: New Rust tests prove write_wav writes the real sample rate (48 kHz ramp + a 5-rate sweep from 8 to 48 kHz) — regression-proof against the hardcoded header.
• 🔁 Startup Sync E2E: Playwright tests verify the selected Whisper engine and microphone are pushed to the backend on boot, reproducing the lost-engine bug exactly.
