feature: Auto-mute YouTube ads (skippable & unskippable)

[dewan-sahib]

Fixes: Issue #3013
This PR introduces a feature to automatically mute audio during YouTube ads (both skippable and unskippable), and restore the user's original unmute state after the ad ends.

Features:

• Detects ad playback using player.classList.contains("ad-showing") + video.duration < 40
• Saves mute state before ad and restores it after
• Works on:
  • Skippable ads
  • Unskippable ads
  • SPA transitions
  • Full page reloads
• Uses a short fallback retry loop to handle late DOM availability
• Controlled by the "Mute Ads" option in the settings UI

Files Touched:

• general.js – Added "Mute Ads" setting to dropdown
• player.js – Added muteAds() logic
• functions.js –
  • Hooked muteAds() into movie_player mutation
  • Added fallback loader for full reloads

Kindly let me know if any changes are needed.

Hello @ImprovedTube , apologies for the delay. I had some personal matters to take care of and was away from open source for a while. I’m back now and will address the feedback within the next week. Thanks for your patience.
