Two more detectors close the analyzer gap list:
mixed_line_endings (warn, tool=02): scans raw bytes for combinations of
CRLF / LF / bare CR. Disaster pattern after multi-source concat
(Windows + macOS + Linux exports stitched together). Operates on raw
bytes only — DataFrame-mode analyze() skips it because raw bytes
aren't available. _load_for_analysis now returns the raw bytes
alongside the DataFrame and repair result so the detector has them.
near_duplicate_rows (info, tool=01): cheap dedup signal — strip and
lowercase every string column, then count df.duplicated(). Catches the
most common case (same customer entered twice with subtle formatting
differences) without paying for fuzzy matching. Anything more
sophisticated stays in tool 01.
Six new tests cover both detectors plus the dataframe-mode skip path.
