Four timing models

Use a simple offset for constant delay, one-point sync for a known correction, two-point drift for affine timing errors, or FPS conversion when timing comes from a frame-rate mismatch.

Zero crossing is explicit

Cues crossing zero are clamped; cues that would sit completely before zero are dropped and counted in the transform report instead of being turned into artificial 1 ms cues.
