[docs.dirac.Ω.D9+] specify the unified Program reference jobs

WHY: Dirac needs one implementable contract for absorbing mature discovery, data-governance, work-management, identity, structure-collaboration, and evidence jobs without copying entities across workspaces.

WHAT: Define eleven reference jobs, canonical chemical and physical identity, independent maturity and work-lane state machines, hard invariants, missing domain objects, phased delivery gates, and end-to-end acceptance scenarios.

VERIFY: reference-system, identity-chain, lifecycle-axis, work/runtime split, current/future split, acceptance-scenario, source-link, and whitespace checks passed.
