fix(ci): resolve cross-platform test failures

- 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.
