Fix Mintlify branding: replace 'Mint Starter Kit' with 'Feel-ix-343 / markdown-oxide'

Summary

Removed broken logo and favicon references fromdocs/docs.json that were causing Mintlify to fall back to its default "Mint Starter Kit" branding. Updated the site name to "Feel-ix-343 / markdown-oxide" to display the correct branding.

The logo files referenced in the config (/logo/dark.svg,/logo/light.svg,/favicon.svg) don't exist in the repository, which causes Mintlify to show its default starter kit branding instead of the intended site name.

Review & Testing Checklist for Human

• Deploy and verify: Check that the Mintlify documentation site now displays "Feel-ix-343 / markdown-oxide" in the header instead of "Mint Starter Kit"
• Confirm intent: Verify this matches your desired branding (text-only vs. custom logo with GitHub icon)
• Visual check: Ensure the header looks correct in both light and dark themes

Test Plan

1. Deploy the changes to the Mintlify site (or check the preview deployment if available)
2. Visit the documentation site and verify the header shows "Feel-ix-343 / markdown-oxide"
3. Toggle between light/dark themes to ensure branding displays correctly in both

Notes

• This change removes the logo/favicon configuration entirely and relies on thename field for branding
• If you want a custom logo with the GitHub icon (as shown in your second image), we would need to create the actual SVG files and add them to the repository
• JSON syntax has been validated
