Heard 1.1.52

• The talk key now interrupts. Press right-⌘ any time Heard is speaking - tap to hush it mid-sentence, hold to talk back. Works in push-to-talk and ambient mode.
• Crystal-clear audio everywhere. Ambient mode no longer switches your Mac into call-mode audio processing - YouTube, system sounds, and narration all stay pristine while hands-free is on.
• The notch now appears right after onboarding completes (no more multi-minute delay on first launch).
