CURVE node (#12757)
* CURVE node

* remove curve to sigmas node

* feat: add CurveInput ABC with MonotoneCubicCurve implementation (#12986)

CurveInput is an abstract base class so future curve representations
(bezier, LUT-based, analytical functions) can be added without breaking
downstream nodes that type-check against CurveInput.

MonotoneCubicCurve is the concrete implementation that:
- Mirrors frontend createMonotoneInterpolator (curveUtils.ts) exactly
- Pre-computes slopes as numpy arrays at construction time
- Provides vectorised interp_array() using numpy for batch evaluation
- interp() for single-value evaluation
- to_lut() for generating lookup tables

CurveEditor node wraps raw widget points in MonotoneCubicCurve.

* linear curve

* refactor: move CurveEditor to comfy_extras/nodes_curve.py with V3 schema

* feat: add HISTOGRAM type and histogram support to CurveEditor

* code improve
