Pull request overview

This PR refactors audio-to-MIDI transcription into a unified extraction pipeline, adds support for the GAME transcription backend (with batching/options), and introduces user-facing algorithm selection plus long-chunk detection/warnings.

Changes:

• Add MidiExtractor<TOptions> base with shared slicing/resampling, progress reporting, batching, and long-chunk confirmation.
• Introduce GAME backend + UI (dialog + view model) for selecting SOME vs GAME and configuring GAME inference/batching.
• Refactor SOME to the new unified extractor API and update localization strings for the new dialog/messages.
