Add native dual Jacobian construction and shared program prefixes Expose symbolic/dual construction in native generation, CLI and thin HEPKit bindings. Compose Symbolica image duals and its native determinant before outer subtraction jets; retain complete face derivatives and saved metadata. Share repeated immutable Jacobian programs within the caller-owned cache. The optional dual path currently supports numerical-dual generation in one through six dimensions. Symbolic remains the default. Record native reuse, physical pointwise parity, current generation tradeoffs and explicit limits. Update the Typst/PDF report with complete fixed D05 generation measurements; dynamic generation and the four timed integration rows remain pending. Validation: 917 workspace tests passed, 33 ignored; strict all-target Clippy, formatting and two post-lint scientific regressions pass. Portable candidate1 suite passes 82 tests; current CLI and thin binding checks are recorded in the audit. No newly installed Python/browser wheel is claimed.
