feat(sandokan): CLI de prueba + fix wire serialization

apps/sandokan (binario `sandokan`): CLI para probar el orquestador.
Subcomandos: daemon, run <exec> [args], list, status, telemetry, stop.

Fix: Intent serializaba Card directo, pero Card tiene un campo
`#[serde(flatten)] extensions` incompatible con postcard ("sequence
length must be known"). Intent::card ahora usa #[serde(with)] que
proyecta Card↔WireCard en el límite de serialización (las extensions
locales se descartan al cruzar el wire — comportamiento correcto).

Smoke test verificado end-to-end: daemon + run /bin/sleep + list +
status Running + telemetry + stop + status Killed.
