Add icon update infrastructure and verify About dialog display

[Copilot]

The About dialog already displays the app icon correctly from LOGO_BLACK_PATH. Added tooling and documentation to enable updating icons from macosicons.com or other sources.

Infrastructure Added

Conversion Scripts

• scripts/convert_icon.sh - Converts PNG to ICNS, iconset (16-1200px), and menu bar variants
• scripts/convert_icon.py - Python alternative with attempted download from macosicons.com API
• test_icon_config.py - Validates icon files, constants, and About dialog implementation

Documentation

• QUICK_REFERENCE.md - 3-step usage guide
• ADDING_ICON_README.md - Detailed walkthrough with troubleshooting
• ICON_UPDATE_INSTRUCTIONS.md - Technical reference for icon formats and manual conversion
• readme.md - Added "Customizing the App Icon" section

About Dialog Implementation

Existing code already correct:

# macos_grok_overlay/app.py:430-438
logo_path = os.path.join(script_dir, LOGO_BLACK_PATH)
icon = NSImage.alloc().initWithContentsOfFile_(logo_path)
if icon:
    icon.setSize_(NSSize(64, 64))
    iconView = NSImageView.alloc().initWithFrame_(NSMakeRect(108, 248, 64, 64))
    iconView.setImage_(icon)
    contentView.addSubview_(iconView)

Usage

# Download icon from macosicons.com, then:
./scripts/convert_icon.sh ~/Downloads/icon.png
python3 run.py  # Verify in About dialog

Network restrictions prevent direct download; manual download required.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• api.macosicons.com
  • Triggering command: /usr/bin/python3 python3 (dns block)
• cdn.macosicons.com
  • Triggering command: /usr/bin/curl curl -L REDACTED -o new_icon.png (dns block)
• macosicons.com
  • Triggering command: /usr/bin/curl curl -L REDACTED -o /tmp/icon_info.json (dns block)
  • Triggering command: /usr/bin/python3 python3 (dns block)
• uxwing.com
  • Triggering command: /usr/bin/curl curl -L REDACTED -o grok_icon.png (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
