fix: add .env.production to bake correct /xm-player/ base path into builds

[ford442]

Summary

• Adds .env.production with VITE_APP_BASE_PATH=/xm-player/
• Vite automatically loads this file during npm run build, so import.meta.env.BASE_URL is correctly baked in as /xm-player/ without needing to manually prefix the env var every time
• Without this, BASE_URL defaults to /, causing all asset fetches (shaders, worklets, .mod files) to 404 on the subdirectory deployment at test.1ink.us/xm-player/

Root cause

The build was run as plain npm run build instead of VITE_APP_BASE_PATH=/xm-player/ npm run build. The deploy.py script documents the correct command but it was easy to miss. This commit makes the correct base path automatic for all production builds.

Test plan

• Run npm run build (no env prefix needed now)
• Check that bundled JS references /xm-player/ asset paths
• Deploy and confirm shaders, worklets, and default .mod load without 404s

The .env.production file now explicitly configures the Vite application base path to /xm-player/, setting the production deployment URL prefix for the mod-player application.

🐰 A path is set, so plain and clear,
/xm-player/ declares right here,
The production stage now knows its place,
With base path routing, apps embrace! 🎵
