Module buffer 

Ropey-backed text buffer module.

This module is split across multiple files to keep each concern small:

• pos.rs: logical positions and selections
• edit.rs: edit representation (char-indexed)
• text_buffer.rs: the TextBuffer implementation (backed by ropey::Rope)
• util.rs: internal helper functions
• tests.rs: unit tests
• prelude.rs: convenience re-exports for downstream crates

Re-exports

pub use text_buffer::TextBuffer;
