reproduce_family no longer hardcodes DataSource::Synthetic: it reads the
family's instrument + window from the persisted manifest and rebuilds the
same local-archive source the dissolved verbs run over; a missing archive
refuses with the verbs' established named-data refusal (exit 1) instead of
silently re-running over wrong data. Sweep families now reproduce N/N
bit-identically; WalkForward families yield a verdict instead of the
empty-OOS-window panic. The synthetic-family path is byte-unchanged.
Accepted minimal duplication: reproduce_family performs its own family
lookup to read the instrument before delegating to reproduce_family_in,
whose signature and unit-test seam stay byte-identical (constraint:
minimal fix).
MonteCarlo reproduce still runs the synthetic seed walk regardless of a
real manifest — pre-existing, semantically distinct (bit-identity over
bootstrap resamples), filed forward.
Verified: both #229 RED tests green over the GER40 archive, full workspace
suite 1107/0, clippy -D warnings clean.
