config(pi): execute pinned native schema and composer oracles

Evaluate raw Pi documents with the vendored upstream TypeBox schema and replay composer/transport expectations captured by actually executing Pi ab366ebe94cacd419d986be454f12b1b9913aaca.

Bind all 252 canonical fields to successful raw and own-layer composer evidence (70 provider, 92 model, 90 override), fail closed where pinned runtime context is unavailable, expose structured inspection, and enforce module/write/restore boundaries with negative fixtures.
