Pull Request Overview

This PR fixes the handling of CRLF (Windows-style \r\n) line endings in the formatter's SourceText implementation. Previously, CRLF sequences were counted as two separate line breaks instead of one, leading to incorrect line counting.

Key Changes:

Modified lines_after() and get_lines_before() methods to properly handle CRLF sequences by consuming both \r and \n as a single line break
Added comprehensive tests for LF-only, CRLF-only, and mixed line ending scenarios
