Struct TextRev 

pub struct TextRev(pub u64);

A single open text buffer. A monotonic counter of TEXT changes to one buffer.

Deliberately distinct from escriba-core’s EditGen, which is a REFRESH generation: that one bumps on every action, including pure cursor moves, because its job is telling the renderer when to repaint. Keying staleness on it would mark every cached offset stale after any keypress — noise, not staleness.

This one bumps if and only if the rope changed, which is the question an offset actually needs answered: “is the text I was measured against still the text?”
