Echo v1.0.3

Fixes

• Hotkey setup now works. The global chord could fail to register on first launch — before Accessibility permission was granted — and never recovered without an app relaunch. It now re-arms automatically once permission is granted, and the Settings recorder shows a clear "Accessibility required" prompt with a fix action instead of silently failing.
• The hotkey is now a single app-wide chord with one editor in Settings → General (was a stale per-profile recorder).
• .paste / .none output modes no longer leak speaker audio.
• Audio frames and utterance markers can no longer reach Gemini out of order.
• Fixed keycode 0 (the A key) being rejected as an unset binding.

Internal

• Removed dead code from the Gemini-only refactor: HotkeyManager, the KeyboardShortcuts/Defaults dependencies, and the unused Silero VAD model + onnxruntime. The download is now ~0.8MB, down from 12MB.
