- Sanity check script (check-codex-global-state.sh) now falls back to
grep -E when ripgrep is not available, fixing the codex-hooks sync
test on all CI platforms. Patterns converted to POSIX ERE for
portability.
- Unicode safety test accepts both / and \ path separators so the
executable-file assertion passes on Windows.
- Gacha test sets PYTHONUTF8=1 so Python uses UTF-8 stdout encoding on
Windows instead of cp1252, preventing UnicodeEncodeError on box-drawing
characters.
- Quoted-hook-path test skipped on Windows where NTFS disallows
double-quote characters in filenames.
