Commit the accumulated working-tree changes as one snapshot. - Headless render: `--render OUT.png INPUT.wav` draws the spectrogram (full window, or `--pane` for the spectrogram pane only) to a PNG with no visible window. Options: `--annotations`/`--no-annotations`, `--annotation-opacity`, `--width`/`--height`. - mLnL annotations: parse the optional `mLnL` RIFF chunk (schema v2) and render tx_frame/assertion/control overlays, a timeline lane, and a waveform-scope echo, with hover tooltips on the spectrogram, timeline, and scope. - sched_offset_ms: parse the per-frame intent->air latency and surface it in the hover tooltips (boxes stay air-anchored upstream). - Supporting: build wiring (rspektrum.make), shared types/headers, web-build and capture-script tweaks, and removal of the old synchrosqueezing LaTeX doc.
