Jose Luis Montañes 7debc7436e initial: code-sinth — DSL-driven modular synth (Python engine + web app)

Patch language with osc/noise/trig/seq/adsr/filter/delay/poly + voice templates
and inline live values. Two runtimes:

- code_sinth/ — Python engine (numpy + sounddevice). Hot-reload via mtime
  watcher. Offline render to WAV. Static-HTTP+WS visualizer (viz/) that
  injects waveforms next to each `node X = ...` line.
- web/ — port of the engine to JS running in AudioWorklet. Single static
  page with CodeMirror 6 editor (line widgets for live waveforms) and a
  control surface on the right with knobs/faders/step_seq/piano_roll
  declared from the patch. State preserved across hot-reload.

 # Bass con barrido: ADSR modula el cutoff de un pasa-bajos resonante.
 # La salida se atenua tambien por la envolvente para tener attack y release de amplitud.
