This PR reduces false regression failures by normalizing non-semantic text differences during comparison.

CRLF and LF line endings are treated equivalently
Trailing whitespace at the end of lines does not cause diffs
Binary files are exempt from normalization

Changes

Updated TestResultFile.read_lines to normalize text output during comparison

Added a focused unit test covering:

CRLF vs LF normalization
Trailing whitespace handling
Binary file exemption

These differences are non-semantic and can introduce noise in regression results, making diffs harder to interpret.

Testing

Added unit tests (tests/test_normalization.py)

Tests pass locally
