Subject: [PATCH 1/2] Optimize _byte_to_line_index

The main optimization here is eliminating the `max(0, idx)` call by handling the edge case directly. Since `bisect_right` returns 0 when `byte_offset` is less than all elements, subtracting 1 gives -1, which we can catch with a simple comparison. This avoids the function call overhead of `max()`.
