Drop the legacy-metadata overlay path (runtimeToolSpecAllowingLegacy,
assembleSchemaRegistryFromBoundAllowingLegacy, metadata-based agent
selection, dry-run seams) so assembly flows exclusively through
ContractFinal; gate MCP fixture machinery behind a build flag so it can
never enter production assembly. Wire output verified identical before
and after; policy tripwire reports 26 products, 847 tools.
Drop misleading Catalog-embed and HintFile naming now that assembly is
declare→delivery and selection comes from ContractFinal.

Move schema authority to declare-time ParamDecl/ContractFinal and
ResolveSchemaBuild so CI/runtime assemble instead of shipping JSON
exclusions/meta-index as delivery sources.
