erdr2pml imports the stdlib `cgi` module, removed in Python 3.13, so its tests were skipped on modern interpreters. Add the `legacy-cgi` backport as a dev dependency so the module imports, and flesh out its tests: deXOR involution, fixKey known vector / length, cleanPML high-ASCII escaping, and sanitizeFileName separator/colon/control-char/angle-bracket handling. The skip guard is kept as a safety net for environments without the backport. Suite is now 44 passing, 0 skipped. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

erdr2pml imports the stdlib ``cgi`` module, which was removed in Python 3.13.
|
|
The ``legacy-cgi`` backport is a dev dependency so the module imports on modern
|
|
interpreters; the skip guard below keeps the suite green if it is ever run
|
|
without that backport (e.g. a bare Python 3.13+ with no dev extras).
