feat(#1708): typed documentation-sourced #853 dispatch-flatten (ADR-1239 Phase B) (#1719)

* feat(#1708): typed documentation-sourced #853 dispatch-flatten

Graduate the #853 orchestrator-backgrounding decision from a scattered RUNTIME==='codex' prose check to a typed, documentation-sourced engine decision. Adds a backgroundDispatch dispatch sub-axis (sourced per host: codex+cursor documented true, 9 documented false, 5 undocumented), shouldFlattenDispatch(dispatch) (inline UNLESS background && backgroundDispatch, fail-closed), and a gsd_run query dispatch-should-flatten the plan/execute workflows call. Cursor is newly background-eligible per its docs (inline->background) — a documentation-justified behavior change. No RUNTIME-name residue for this decision.

* fix(#1708): address review findings on typed dispatch-flatten

Code/adversarial review: convert the manager.md/autonomous.md Compound Action preamble from hardcoded 'On Codex' to FLATTEN-based branching (the handlers already use the query; the preamble contradicted them and was wrong for cursor); make shouldFlattenDispatch null-safe + type-honest (accepts raw 'undocumented' registry values); make backgroundDispatch a required descriptor field (matching its siblings, all 16 carry it); strengthen the config.runtime behavioral test; update the bug-853 prose-pin test + comment. Security review clean; Codex confirmed no fail-open.

* test(#1708): backfill backgroundDispatch in role:runtime test fixtures

Making backgroundDispatch a required descriptor field broke role:runtime fixtures in capability-manifest-version/capability-registry/host-integration-descriptors tests that build a dispatch object without it (caught by full gsd-test, not scoped npm test). Backfill backgroundDispatch:false into the well-formed fixtures; the deliberately-malformed 'required-field' test fixture is left malformed by design.

* test(#1708): update fix-1521 dispatch-gating assertion to the FLATTEN gate

fix-1521 pinned the codex-specific run_in_background prose that #1708 graduated to the typed dispatch-should-flatten/FLATTEN gate. Update its assertions to verify FLATTEN=false gating (not a runtime name) + that the old RUNTIME===codex gate is gone. Caught by full gsd-test.

ADR-456 requires every allow-test-rule exemption to carry a see #NNN reference; the source-text-is-the-product annotations added when migrating the prose assertions lacked it (lint-tests CI gate). Add (see #1708).

### Compound Action (background + inline)

When the user selects a compound option, behavior depends on whether the runtime supports background dispatch of nesting-capable orchestrators — the Plan Phase N / Execute Phase N handlers below resolve it via `gsd_run query dispatch-should-flatten` (#1708):
- **On Codex:** **Spawn all background agents first** (plan/execute) — dispatch them in parallel using the Plan Phase N / Execute Phase N handlers below — then run verification actions, then run the inline discuss; the background agents continue while you verify/discuss.
- **On Claude Code or any other non-Codex runtime:** run the chosen plan/execute step(s) **inline** via their handlers below (in order), then run verification actions, then run the inline discuss. There is no overlap.
- **If `FLATTEN` is `false` (the host can background a nesting-capable orchestrator — e.g. codex, cursor):** **Spawn all background agents first** (plan/execute) — dispatch them in parallel using the Plan Phase N / Execute Phase N handlers below — then run verification actions, then run the inline discuss; the background agents continue while you verify/discuss.

### Plan Phase N
Planning runs autonomously. **First resolve the runtime.** Background dispatch is only safe on a runtime where a backgrounded agent can still nest the pipeline's subagents (plan-checker / worktree executors / verifier). Among supported runtimes only **Codex** (`spawn_agent`) can do this; Claude Code's backgrounded agents have no `Agent`/`Task` tool, and every other runtime either prohibits nested subagents or disables them by default. So run **inline** everywhere except Codex, which is dispatched in the background.
