feat(playground): MIDI CC device presets + bug fixes
Add MIDI CC preset system for bundled device configurations: - midi-cc-presets.js: listPresets/loadPreset/loadPresetFromFile API - presets/polybrute.json: Arturia PolyBrute CC map - Preset selector in quick controls bar and MIDI CC drawer - File import button for loading JSON presets from disk Bug fixes in a-app.js: - Destroy IML instances before resizeMLP() to free WASM memory - Fix randomiseWeights() call (was drawWeights()) - Fix thumbs-up to store rawParamValues instead of post-pipeline outputs
