chore: stop stat'ing assets whose sizes nothing reads

[anurag6569201]

builder.mimeTypes stats every server asset for a size it never returns, and create_assets stats every file in static/ for a size field nothing reads. Both calls are removed.

Summary by CodeRabbit

• Performance

  • Reduced unnecessary filesystem checks when processing static and server assets, improving build efficiency.

• Bug Fixes

  • Simplified asset metadata by removing file-size information that was not needed.
  • Asset records now retain relevant file paths and MIME types without exposing size values.
