Project card overlay: inherit accent color for GitHub icon and separator

[Copilot]

Project card overlays were rendering the GitHub icon and / in --text instead of the card’s accent color. This updates the overlay label so icon, separator, and project key all inherit the same parent color.

• Scope

  • Updated only src/routes/+page.svelte in the project-card overlay label block.
  • No other sections or styling logic were modified.

• Change

  • Removed text-(--text) from the inline icon and separator elements so they inherit the parent color (langColorTable[..].primary).

• Before / After

  <!-- before -->
  <i class="fa-brands fa-github text-(--text)"></i><span class="text-(--text)">/</span>{key}
  
  <!-- after -->
  <i class="fa-brands fa-github"></i><span>/</span>{key}
