Pass target inputs positionally and normalize every retained
`functools.partial()` layer, including Python 3.14 Placeholder
binding. Validate the complete target signature before startup.
Route each ordinary async fn through a static `@context` endpoint
so remote results, errors and caller cancellation remain linked.
Send namespace and function components separately, then resolve
through `Actor._get_rpc_func()` so the RPC module allowlist remains
authoritative. Retain client-created `NamespacePath` refs so
`to_tuple()` does not re-import their callable.
Owned actors enable the endpoint's `__name__` directly. Keep
`to_actor.MODULE` as the importer-facing alias used by caller-owned
portals while retaining the target module's authorization boundary.
Cover all placement modes, nested partials, argument collisions,
linked cancellation, remote errors and authorization failures.
Caught-during: review remediation
