Detailed Description

Directory-backed frame sinks for CA trajectories.

Directory_Frame_Sink writes selected simulation frames into a directory using the Phase-11 exporters from ca-io.H and ca-tikz.H. It is small enough to be used directly in an engine post-step hook or in an explicit simulation loop.

No compression or video dependency is pulled into Aleph-w. The sink writes a deterministic manifest and exposes montage_command_hint() so callers can hand the frame sequence to external tools such as ffmpeg or NetPBM.
