Circuitry flattens grouped value boundaries.

Packages expose surfaces and return YAML fields.

Zinc:

• reads Circuitry-discovered value-boundary mappings
• follows surface refs to package surfaces
• advances mappings whose inputs are available
• carries the active run values while execution advances
• records package installs and surface invocations in Limbo

packages, surface, and preserve are Zinc fields, not Circuitry fields.
