Reads a `DTree` value as a floating-point number.

String values are parsed using the same permissive conversion rules used by the runtime's scalar helpers. Boolean values become `1.0` or `0.0`.

Use this for numeric config values, JSON-decoded fields, component props, and request data that should be treated as a number.
