3//! Replace an open model's content. Increments `Version`,
4//! recomputes `Lines`, marks `IsDirty=true`. Mirrors VS Code's
5//! `TextDocument.update(...)` semantics - the Monaco model
6//! observers see a single coherent edit, not partial state.
7//!
8//! Errors when the URI isn't open; callers must `ModelOpen`
9//! first.
