- An inverted clip's roundtrip record goes in the filter's extension
dictionary through the codec's own API (ensure_extension_dictionary /
xrecord / extension_dictionary_handle) instead of a scan of every
object, which the renderer ran for each clipped reference.
- Pin cadcodec 1c3be0c (the DXF writer now links a spatial filter's
extension dictionary, so that record is not left unreferenced) and
cadkernel deb529b; plugin crates and the Python plugin lock follow.
- The XCLIP boundary preview stays f64.
