Pull request overview

This PR changes the color used for the voice recording icon/animation in the chat interface from ACTIVITY_BAR_BADGE_BACKGROUND (blue notification badge color) to ACTIVITY_BAR_FOREGROUND (white active item color) to provide better visual distinction and semantic correctness for the recording state indicator.

Key Changes

• Updated the color constant from ACTIVITY_BAR_BADGE_BACKGROUND to ACTIVITY_BAR_FOREGROUND for the active recording animation

Thanks!

@mrleemurray maybe you could also chime in for this color change: the idea is to show the active voice recording icon in a stronger "active" color, that is why I picked the badge color, which is blue in most default themes. But that does not work in all themes, as this issue shows.

[mrleemurray]

I'll investigate an alternative color that is compatible in all themes

I think @dmitrivMS color choice works well - great job!
