Version 1.7.3 - Bug Fixes and ConcreteInfo Themes

Fixed critical file opening bug and theme visibility issues, plus added ConcreteInfo branded themes.

Bug Fixes:
• Fixed double-click file opening race condition
  - Removed setTimeout logic from did-finish-load handler
  - Now relies solely on renderer-ready IPC signal for proper initialization
  - Files from Windows Explorer now open correctly on first attempt

• Fixed theme preview text visibility for 14 themes
  - Added proper .pane:last-child background overrides
  - Fixed dark text on dark backgrounds and light text on light backgrounds
  - Affected themes: Dracula, Nord, One Dark, Atom One Light, Material,
    Gruvbox Dark/Light, Tokyo Night, Palenight, Ayu Dark/Light/Mirage,
    Oceanic Next, Cobalt2

New Features:
• Added 3 ConcreteInfo branded themes
  - Concrete Dark: Very dark theme with orange accents
  - Concrete Light: Light theme with orange accents
  - Concrete Warm: Mid-tone gray theme with orange accents
  - All themes use ConcreteInfo brand colors: #0d0b09, #464646, #9a9696, #e3e3e3, #e5461f

• Updated theme count from 19 to 22 themes
