fix: stop opening .sln/.mts/.gsm developer files as media

[twangodev]

Removes the .sln, .mts, and .gsm extensions that hijacked Visual Studio solution files, TypeScript sources, and ArchiCAD objects into the media player; raw signed-linear audio is re-registered under the non-colliding .slin. Fixes #78.

Summary by CodeRabbit

• Bug Fixes
  • Improved media type recognition for raw audio files, including support for the slin extension.
  • Updated video file detection so transport-stream related extensions are less likely to conflict with TypeScript files.
  • Refined the IDE’s media file recognition list to match the latest supported extensions.

Walkthrough

Updates shared media classification so .mts is no longer video and raw-audio uses .slin, then aligns the transcoder and IntelliJ media extension lists with the new names.

Poem

I hopped through the media burrow at night,
Past .sln and .mts with a twitchy delight.
Now .slin hums softly, all tidy and neat,
And TypeScript files stay safe from my feet.
