open-prose skill 0.17.0

Added

• prose init and prose compose now provide guided, progressive program
  architecture. The obligation-centered std/ops/compose directory package
  keeps the architect focused on a bounded conceptual frontier, materializes
  settled decisions into one canonical Contract package, derives a disposable
  visual view, and creates semantic tests outside-in from the package promise
  through Contract boundaries, failure behavior, harness portability, and
  performance. Framework pressure discovered during composition is routed to
  deduplicated public issues rather than implemented in the target program.
