Summary by cubic

Rewrites the active roadmap so the repository has a defined finish line, and links it from the root README.md.

  • Marks presentation infrastructure and the causal-inference expansion as complete, and defines the remaining work: PR #125, Principal Stratification, Time-Varying Treatments/Marginal Structural Models, and a final consolidation.
  • Adds an explicit hard stop after consolidation, after which the causal-inference domain enters maintenance mode and new decks require a roadmap decision.
  • Describes a finite process for any future domain expansion and moves accessibility and citation work to a later roadmap cycle.
