Title

Add persistent voice-reactive overlay + customization improvements (v1.3.6)

Description

This PR introduces a new persistent on-screen overlay feature for MicMute, then follows up with several polish/fix passes based on real testing.

Main feature (new)

This is the big change in this PR:

• Added a persistent overlay that stays visible on screen and reacts to mic/voice state.
• Overlay states:
  • Green when voice is detected
  • Gray when no voice is detected
  • Red when microphone is muted
• Added a dedicated Overlay tab in settings with controls for:
  • Position
  • Size
  • Opacity
  • Behavior options (lock on startup, topmost behavior, click-through, resize with wheel, etc.)

Extra improvements added during testing

After adding the feature, we improved reliability and UX with a few follow-ups:

• Added configurable overlay hotkeys:
  • Lock/Unlock (default: Ctrl+Alt+F10)
  • Find/Move overlay near cursor (default: Ctrl+Alt+F11)
• Both hotkeys can now be disabled by leaving them empty (Record -> Stop with no key).
• Added OSD feedback when lock/unlock is triggered by hotkey:
  • Overlay Locked
  • Overlay Unlocked
• Fixed overlay UI/layout regressions and callback issues discovered during validation.
• Added/kept logging improvements to make troubleshooting easier.

Release prep

• Version bump to 1.3.6
• Added CHANGELOG.md
• Updated README overlay section (including find hotkey and custom/disable hotkeys)

Quick test checklist

• App builds and launches.
• Overlay is persistent and visible.
• Overlay changes color correctly by voice/mute state.
• Overlay can be moved/resized/unlocked/locked.
• Custom hotkeys can be recorded and saved.
• Empty hotkey disables action as expected.
• Lock/unlock hotkey shows OSD feedback.

Thanks for reviewing!
