Fix Language detection problems

This fixes language detection issues for large and asset-heavy repositories. It bumps the tight HTTP timeouts from 1s to 5s, adds a 10,000 file cap to prevent knot starvation on massive codebases, and drops enry.Unknown files from the language calculations. The unknown file exclusion prevents massive game assets (like Godot .tscn files) from washing out actual code languages like GDScript in the breakdown.
