Reorganize components into category folders (forms/canvas/overlays/etc.); add the media-editor headless family (timeline, curve-editor, waveform, crop, color picker, etc.); apply perf fixes (O(1) collection lookups, plain-object drag state, gesture-leak teardown, shallowRef color state, rect caching) and replace source `any` with proper types.
