Configure Linguist to exclude data and generated files

[Copilot]

Repository language statistics are skewed by data files and auto-generated content.

Changes

Added .gitattributes with linguist-generated markers for:

• Lock files: yarn.lock (818KB), package-lock.json
• Data files: All JSON in apps/web/src/data/ including ecosystem.json (4,778 lines) and 600+ ecosystem metadata files
• Generated code: premintsMapping.ts (1,829 lines of key-value mappings)

This excludes ~6,600 lines of data and generated content from language statistics, providing accurate representation of the TypeScript/JavaScript codebase.

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:

• https://api.github.com/graphql
  • Triggering command: /usr/bin/gh gh issue list --limit 10 (http 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)
