Add operating-point simulation props

[ShiboSoftwareDev]

Summary

• allow <analogsimulation> to select DC operating-point or transient analysis
• add a parsed simulation timeout and pass it through the shared SPICE engine interface
• let chips explicitly opt into being an analog simulation boundary, so missing models can be diagnosed separately
• regenerate the public prop documentation
