+feat(packages): edit a package manifest via `PATCH /packages/:id`
+
+Adds an editable path for a package's `name` / `description` / `version` after
+creation: `SchemaRegistry.updatePackageManifest` (merges in-memory, preserving
+lifecycle state), `protocol.updatePackage` (re-persists to `sys_packages`), and
+the `PATCH /packages/:id` route in the HTTP dispatcher. `id` / `scope` / `type`
+remain immutable.
