Add extension icons and dynamic badge colors based on tab count

[Copilot]

Plan: Add Icon and Dynamic Badge Colors

• Create minimal and unique icon for the extension (SVG format)
• Update manifest.json to reference the SVG icon
• Modify background.js to implement dynamic badge colors based on tab count:
  • < 25 tabs: bright green (pastel #A7F3D0)
  • < 50 tabs: dark green (pastel #6EE7B7)
  • < 75 tabs: yellow (pastel #FDE68A)
  • < 100 tabs: orange (#FB923C - more dramatic)

  • = 100 tabs: red (#F87171 - more dramatic)

• Run code review and address feedback
• Run security scan (no vulnerabilities found)
• Create testing documentation
• Address feedback: Change to SVG format with new minimal design
• Address feedback: Make orange and red colors more dramatic

Summary

All requirements have been successfully implemented:

1. Minimal SVG Icon: Created clean three-bar tally counter design in SVG format
2. Dynamic Badge Colors: Implemented color scheme with more dramatic orange and red for higher tab counts
3. Code Quality: Passed code review and security scans with no issues

The extension uses a single optimized SVG icon that scales for all sizes (16px, 48px, 128px), and the badge colors now provide better visual feedback with more vibrant warning colors.

Original prompt

1. create minimal and unique icon for this extension
2. set badge color with pastel pallete base on this criteria
   < 25 tabs bright breen
   < 50 tabs dark green
   < 75 tabs yellow
   < 100 tabs orange

= 100 tabs red

Changed to SVG format with a new minimal three-bar tally counter design. The icon now uses a single scalable SVG file (icon.svg) for all sizes.

@copilot make orange and red a little more dramatic

Made the orange and red colors more dramatic:

• Orange (< 100 tabs): #FB923C (was #FCD34D)
• Red (>= 100 tabs): #F87171 (was #FCA5A5)
