impl PositionExt for Position

fn point(&self, document: &Document) -> Point

LSP positions use a zero-based line index for line and a UTF-16 code-unit offset within that line for character.

Ropey and Tree-sitter, however, operate on UTF-8 byte offsets. To bridge this mismatch, we take the line number directly as the Tree-sitter row, then look up the corresponding line in the Rope and convert the UTF-16 character offset into a char index and, from there, into a UTF-8 byte offset for the column.

The resulting (row, column) byte position is then used to locate the node in the syntax tree.
