Subject: [PATCH 1/3] Fix test_sensitive_word failing on Windows

Replace shell-based search (powershell Select-String / grep) with pure
Python pathlib.rglob + read_text. The PowerShell implementation output
relative paths while the regex expected absolute paths, causing the test
to always return empty results on Windows.
