TP-26 — Sync custom window chrome with active theme

[ZhuchkaTriplesix]

Epic: E
Depends on: TP-17

Source: docs/theme-parser-github-issues.md

Goal

Ensure title bar / window controls follow custom theme background/canvas.

Files

• lib/main.dart
• lib/features/main_screen/main_screen.dart
• any title bar/window button widgets.

Implementation

Find where bitsdojo_window title area and window controls are styled.

Use:

• QueryaThemeScope.of(context).workbench.canvas
• QueryaThemeScope.of(context).workbench.surface
• QueryaThemeScope.of(context).workbench.mutedForeground

Avoid:

• direct singleton reads inside deep widgets when inherited theme is available;
• app-wide notify on hover.

Acceptance Criteria

• Switching theme updates title bar background.
• Window buttons remain readable.
• Hover states use theme tokens.

Tests

• Widget test if title bar is testable.
• Otherwise manual smoke checklist in PR body:
  • dark;
  • light;
  • custom dark;
  • custom light.
