Update favicons for light/dark mode contrast

[patcapulong]

Summary

• Replace favicon SVGs with new transparent-background versions (no more solid background rects)
• Fix light/dark mode mapping in docs.json so dark icon shows in light mode and light icon shows in dark mode for proper contrast

Test plan

• Verified locally on localhost:3004 with light/dark mode toggle

Made with Cursor

Greptile Summary

Fixed favicon display by removing solid background rectangles from SVGs and correcting the light/dark mode mapping in docs.json. Previously, the config incorrectly showed dark icons in light mode and vice versa - now light mode displays favicon-light.svg and dark mode displays favicon-dark.svg for proper contrast.

• Removed background <rect> elements from both favicon SVGs for transparent backgrounds
• Swapped favicon mapping in docs.json to match mode names correctly
• Made minor coordinate adjustments to the SVG paths

Confidence Score: 5/5

• This PR is safe to merge with no risk
• Simple visual update to favicon files with straightforward config fix - no logic changes, no runtime behavior affected
• No files require special attention
