Description: describe-method-wire-through Summary Wire the new DESCRIBE METHOD [EXTENDED] ... statement through the planner, executor, and MCP surface, using the parser AST node from stackql-parser v0.0.16-alpha02 and the resolver formulation.IntrospectMethod from any-sdk v0.5.2-beta05. The new statement travels through its own code path: a handleDescribeMethod dispatch in the plan builder resolves the resource directly via handlerCtx.GetProvider + prov.GetResource (no table-metadata hierarchy), and a new NewDescribeMethodInstructionExecutor calls the resolver and renders rows with d keys so the default row sort preserves resolver order. Existing DESCRIBE TABLE behaviour is byte-identical. Expose the introspection via MCP: new describe_method tool on the Backend interface, implemented on both the standard and reverse-proxy backends, with a DescribeMethodInput DTO carrying method_path and extended. Implementation notes Added matching case *sqlparser.DescribeMethod branches to every astvisit/early-analysis/router site that already had a *sqlparser.DescribeTable branch (13 files). Taxonomy's three sites return an explicit "dispatched outside of hierarchy resolution" error to make accidental fall-through loud. Fixed a pre-existing import cycle introduced by the WIP MCP changes (primitivebuilder/shortcuts.go -> cmd -> tsm_physio -> ... -> primitivebuilder) by extracting build-time identifiers to a new leaf internal/stackql/buildinfo package. cmd/root.go's init() mirrors its -ldflags-populated vars into buildinfo, so existing -X github.com/stackql/stackql/internal/stackql/cmd. flags in CI keep working. Test plan go build --tags sqlite_stackql ./... clean go test --tags sqlite_stackql ./... clean; no regressions in the 45s driver suite Four new Go integration tests in internal/stackql/driver/describe_method_integration_test.go pass: simple get, extended insert (description + body-renamed data__name as input_required), delete (zero output rows), unknown method (resolver error path) Sample output confirms deep nesting (iamConfiguration.bucketPolicyOnly.enabled preserved in shape column) and the resolver's input-then-output ordering Robot suite green via python cicd/python/build.py --robot-test (CI) - includes six new DESCRIBE METHOD cases plus the non-negotiable Describe Table Still Works Unchanged regression guard Manual smoke: stackql exec "DESCRIBE METHOD google.storage.buckets.get;" and the EXTENDED variant Manual: MCP describe_method tool returns expected row structure when called from an MCP client
