fix: replace LaTeX .gitignore with Go-specific patterns

The template .gitignore contained 327 lines of LaTeX-specific patterns
which are irrelevant for a Go relay server project.

Replace with patterns for:
- Go binaries and vendor directory
- SQLite database files (data/, *.db, WAL/journal files)
- IDE configuration files
- OS artifacts (.DS_Store, Thumbs.db)
- Environment files (.env)
- Build output (dist/)
