galdr 0.1.0: terminal grid synthesizer (MIDI in, PipeWire out)

Signal flows downward through single-glyph unit generators; each MIDI note
voices the whole grid; the mix renders low-latency to PipeWire (reusing the
native path from spectrust). Grid edits recompile and hot-swap without
dropping audio. Pairs with orca (note/CC source) and spectrust (visualizer).
