Merge origin/master: adopt the DeepSeek Harness SDK product name

Reconciliations beyond textual conflicts:
- product rename (DeepSeek Code -> DeepSeek Harness SDK) applied to the
  PR-added assertion in system-prompt.spec.ts that master's rename
  commit could not reach
- architecture.md: master's rewrite kept; this PR's prompt-assembly
  semantics re-added in the new doc's voice (Turn Flow footnote +
  service-spine row), within the 1630-word ceiling
- cordis catalog regenerated into master's split events.md/services.md
  (events-and-services.md deleted); module graph and doc graphs
  regenerated to pick up this PR's new events and dependency edges
