Pull request overview

Adjusts Agent Session titlebar status widget styling so its background does not change when debug mode updates Command Center colors.

Changes:

• Replaces var(--vscode-commandCenter-background) with fixed translucent rgba(...) backgrounds for the agent status pill and badge.
• Adds .vs and high-contrast (.hc-black, .hc-light) overrides to tweak/disable the fixed background.

• Same concern as above: replacing var(--vscode-commandCenter-background) with a hardcoded rgba value will ignore theme overrides for commandCenter.background, so the badge can visually diverge from the Command Center in custom themes. It would be more robust to continue using the theme token here and address the debug-mode override at its source (by not overriding commandCenter.background globally, or by introducing a dedicated debug-only token/variable).

	background-color: rgba(255, 255, 255, 0.05);
	border: 1px solid var(--vscode-commandCenter-border, transparent);
	flex-shrink: 0;
	-webkit-app-region: no-drag;
	margin-left: auto;

This should probably be themable?

[joshspicer]

@bpasero Is there a correct CSS variable you think makes sense here? var(--vscode-commandCenter-background) is difficult as it changes to the debug color and I wasn't certain how to make changes to it safely to special case my widget

I figured it out

@copilot fix this PR sitll be themeable but not have the problem of changing to the 'debug' color

[Copilot]

@joshspicer I've opened a new pull request, #292944, to work on those changes. Once the pull request is ready, I'll request review from you.

It is now themeable
