Migrate from Clearbit Logo API to Logo.dev with token authentication

[Copilot]

Clearbit Logo API is being replaced with Logo.dev. All logo fetching now uses Logo.dev's authenticated API with the provided public key.

Changes

• lib/SiteMapper.hs: Updated default logo URL from logo.clearbit.com to img.logo.dev with token parameter pk_CRpvkunsQi2ojaUrvTgQZA
• lib/TemplateEngine.hs: Fixed URL construction to handle paths with/without leading slash correctly (eliminates double slashes)
• template.html: Added Logo.dev attribution footer per API requirements
• links.txt: Updated documentation references and explicit logo URLs
• test/TemplateEngineSpec.hs: Updated assertions for new URL behavior

Example Output

-- SiteMapper.hs: Default logo generation
replacementLogo = Url
  { protocol = "https://",
    hostname = "img.logo.dev",
    path = "/" ++ hostname parsedUrl ++ "?token=pk_CRpvkunsQi2ojaUrvTgQZA"
  }

Generated HTML:

<img src="https://img.logo.dev/github.com?token=pk_CRpvkunsQi2ojaUrvTgQZA" />

Note

Also updated base dependency to ^>=4.21.0.0 for GHC 9.12.2 compatibility (unrelated build requirement).

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:

• img.logo.dev
  • Triggering command: curl -I REDACTED (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)

Original prompt

Help me migrate from Clearbit Logo API to Logo.dev. Here's what I need to do:

1. Find and replace all instances of 'https://logo.clearbit.com/' with 'https://img.logo.dev/' in my codebase
2. Sign up for a Logo.dev account at https://www.logo.dev/signup and get my public key (starts with pk_)
3. Add the token parameter to all logo URLs: https://img.logo.dev/stripe.com?token=YOUR_PUBLIC_KEY
4. Update my attribution link to: Logos provided by Logo.dev
5. Test that logos display correctly before deploying

Please help me search my codebase for Clearbit references and update them to use Logo.dev.
