Type any unit into SliderControl / MetricControl fields — "6ft", "180cm",
"1m80", "5'11\"", "72in", "45°", "1.57rad" — and it canonicalizes to the
unit the field already stores (meters / degrees / radians / inches),
independent of the metric/imperial display toggle. A live "= 1.83 m" hint
previews the parsed value while typing.
Only the typed-text commit path changes: drag-scrub, wheel, and arrow-key
editing are untouched, and any unit the adapter doesn't recognise (%, unitless,
rad/s) falls back to Number.parseFloat, so nothing regresses. The shared
lib/measurement-parser.ts maps each field's `unit` prop to a lingo kind +
canonical unit, covering the auto-inspector and every custom panel at once.
