Deepen query dispatch seam with Command Topology Module (#3078)

* Deepen query dispatch seam with command topology module

* Stabilize SDK parity defaults and integration test gating

* docs(architecture): record pre-project config policy and e2e gate

* refactor(query): stop injecting native adapter in CLI dispatch path

* fix(config): align workflow auto-chain typing and docs

+**Query command dispatch deepened with Command Topology Module** — query dispatch now consumes a single topology seam that resolves command tokens, binds native handler adapters, and returns structured no-match diagnosis, improving locality and reducing dispatch seam drift.

 ### Query Command Resolution Module
 Canonical command normalization and resolution Interface (`query-command-resolution-strategy`) used by internal query/transport paths after dead-wrapper convergence.

+### Command Topology Module
+Module owning command resolution, policy projection (`mutation`, `output_mode`), unknown-command diagnosis, and handler Adapter binding at one seam for query dispatch.
+
+### Query Pre-Project Config Policy Module
+Module policy that defines query-time behavior when `.planning/config.json` is absent: use built-in defaults for parity-sensitive query Interfaces, and emit parity-aligned empty model ids for pre-project model resolution surfaces.

 - Extracted **Native Dispatch Adapter Module** so Dispatch Policy consumes a stable native dispatch Interface (not closure-wired call sites).
 - Extracted **Query CLI Output Module** to own projection from dispatch results/errors to CLI output contract.
 - Converged internal command-resolution and policy imports onto canonical modules and removed dead wrapper modules.
+- Added **Command Topology Module** as dispatch-facing seam that resolves commands, projects command policy, binds handler Adapters, and emits no-match diagnosis consumed by Dispatch Policy.
+- Locked **pre-project query config policy** for parity-sensitive query Interfaces: when `.planning/config.json` is absent, use built-in defaults and parity-aligned empty model ids for model-resolution surfaces.
+- Gated real-CLI SDK E2E suites behind explicit opt-in (`GSD_ENABLE_E2E=1`) to keep default CI/local verification deterministic while preserving full-path validation when requested.
