Native now serves DELETE /api/namespaces/{namespace}, which dw namespace:delete and the published SDK's deleteNamespace call. It follows published PHP's NamespaceController::destroy over NamespaceLifecycleCleanup.

Behavior

• One transaction deletes every row the namespace owns, in PHP's order. Each table is matched by the run, instance or namespace columns the verified schema has, as PHP's column checks select them; run summaries, for instance, go by instance.
• The response is 200 {name, status: "deleted", deleted}, with each table's non-zero count under PHP's keys.
• Native also clears its own poll receipts and worker incarnations for the namespace. PHP has no such tables, so they are not reported.
• A missing namespace answers PHP's 404 namespace_not_found (Namespace [name] not found.).
• Deleting needs an admin, as updating does.
• Explicit refusal. Native cannot delete external payload objects yet. A namespace that still references any, in the registry or in its runs' payload columns, refuses with PHP's 503 external_payload_storage_driver_unavailable and changes nothing.

Fixture first. The new reviewed namespace-delete fixture uses the unchanged published PHP SDK. The namespace holds one search attribute definition and one started, unclaimed run. The fixture checks:

• the exact counts: one command, two history events, one task, one definition, one run summary, one run and one instance;
• the 404 on read and on a second raw delete;
• the SDK's typed ServerException 404 for the SDK's own second delete;
• that a run in another namespace remains, and the deleted run's workflow ID starts again.

PHP fills its timeline, timer and lineage projections asynchronously, so those counts may be absent or positive. Embedded declares HTTP namespaces inapplicable.

Evidence

• The probe ran locally against the frozen published PHP 2.5.14 image on SQLite, and checkNamespaceDelete accepted the observation. Those counts are the fixture's expected values.
• ServerParityNamespaceDeleteContractTest.mjs passes 18/18: the PHP observation, counted projections and embedded pass, and 15 mutations are refused.
• The native tests delete a namespace with exactly PHP's counts and refuse while external payloads remain, on SQLite, PostgreSQL and MySQL.
• The full SQLite suite with --all-targets passes: 228 unit tests and 396 execution tests.
• Shared Server fixtures will run it against published PHP, embedded and native here.

Merged into the #675 train at 1448737bb. Re-checked locally against the new PHP 2.11.1 reference: the namespace-delete fixture passes on PHP, embedded (inapplicable) and native, and the three-way comparison passes. Sonar's duplication gate now passes after the store_methods! change. This PR closes when the train lands.
