docs(archon): flip integration design + setup to shipped; record real-API findings

[Velascat]

Summary

OC #85 + ER #6 landed the Archon real-workflow integration on 2026-05-07. Same-day live validation against a built-from-source container surfaced three findings; this PR folds them back into the canonical docs.

Changes

docs/architecture/adapters/archon-real-workflow-integration.md

• Status flip: Approved design — implementation pending → Shipped 2026-05-07 with PR refs (OC #85, ER #6).
• Workflow-name table corrected to the real bundled defaults Archon ships: archon-assist, archon-fix-github-issue, archon-test-loop-dag, archon-refactor-safely. Earlier-draft archival note kept inline so history is visible. The matching code change ships in Velascat/OperationsCenter#TBD.
• New "Real-API findings (2026-05-07 live validation)" section documenting:
  • F1 — workflow-name divergence (now fixed in OC).
  • F2 — /api/workflows is cwd-scoped: empty without ?cwd= linking to a registered codebase. Dispatch-by-name still works.
  • F3 — kickoff returns 200 + {accepted, status:"started"} exactly as the AsyncHttpRunner upgrade predicted.

docs/operations/archon-setup.md

• deferred / health-only probe wording → shipped wording with cross-link to the design doc + Real-API findings section.
• runtime_kind documented as http_async (production path); ABC + ManualRunner closure path noted as test-only.
• --list-workflows usage documented including the expected "no workflows returned" signal against a fresh container (cwd-scoped discovery; not a bug).
• Deferred section refreshed: auto-approve policy, SSE streaming, and the new --cwd flag enhancement on the operator probe.

Test plan

• Doc-only PR; no code changes.
• Companion code change in Velascat/OperationsCenter#TBD (DEFAULT_WORKFLOW_NAMES + tests).
• Cross-references to OC #85 / ER chore(.console): rename to standard pattern (task/guidelines/log/backlog) #6 verified.
