A piped stdout on Windows defaults to the ANSI code page (cp1252 on most
Western installs). rank_state.py printed titles and companies with
ensure_ascii=False, so one Cyrillic, CJK, Devanagari, Polish or Turkish
posting ended /rank with UnicodeEncodeError. job_key --audit, salary_lookup,
convert_salary_excel and verify_layout failed the same way.
Each tool now reconfigures stdout and stderr to UTF-8 at entry. The new
tests run every tool in a child process with a cp1252 stdout forced through
PYTHONIOENCODING, so Linux CI reproduces the Windows failure.
