Añade campos params y output al frontmatter YAML de las 506 funciones del registry. Cada parámetro tiene descripción semántica (qué representa, unidades, rango típico) y cada función describe qué produce su output. Permite a agentes razonar sobre cadenas de composición (ej: prices → log_return → sharpe_ratio) sin leer código.

Sale con exit code 0 (success), 1 (failure) o 2 (partial). Con --strict mapea partial a failure."

## Notas
|
|
|
|
Requiere `yq` (v4+, modo expression `-e`) y `jq` (o la implementacion printf de report_execution_json). Solo soporta `action: command` — otros actions se marcan como error del paso. El campo `timeout_ms` por defecto es 30000 (30s); si el comando excede el timeout, `timeout(1)` sale con exit code 124 y se registra el error correspondiente. El output del comando (stdout+stderr combinados) se sanitiza reemplazando tabuladores y saltos de linea por espacios antes de escribir al TSV temporal. Las funciones `exit_with_status` y `report_execution_json` se cargan via `source` desde el mismo directorio que `run_steps.sh`.
