refactor(javascript): share the reconstruction input contract

Remove the reconstruction-only request schema and consume the canonical parsed
JavaScript application input. Production already owns parsing at the service
boundary; direct test seams now use that same schema instead of a weaker path
contract. Preserve format, filesystem, source selection and lifecycle validation.

Add a NUL-path regression for canonical admission and typed input-error
projection. Verified 63 focused cases plus static, build, docs, discovery and
duplication checks; no target execution or real-provider claims.
