…zer crash Three independent binding-correctness fixes, previously bundled in the channel-safety PR: - wrappers/per_frame_port: derive a dynamic frame port's channel count from the buffer the host handed us when the host never ran the channel manager (Python/GStreamer/Pd one-block drivers left it 0, which copied nothing and left the output uninitialised). - gstreamer/texture_filter: stop fixate_caps collapsing the src caps to 1x1; copy the input width/height to the output. - touchdesigner/chop/audio_processor: fix the crash on audio->control analyzers (objects with zero audio-output busses).

Three independent binding-correctness fixes, split out of the former channel-safety mega-PR (#143) so each is reviewable on its own.
channelsat 0, which copied nothing and left the output uninitialised (garbage).fixate_capscollapsing the src caps to 1×1; copy the input width/height to the output.No dependency on the zero-fill invariant (#142); these are separate files.
