Dario Gabriel LipicarandClaude Opus 5 1be71bbbeb feat(sdk): make the by-name call path a supported API
The dynamic (by-name) invoke path already existed and was already ungated at
every layer — lp_client_create / lp_invoke in the C ABI, logos::LpClient above
it, and the Qt client above that. Nothing checked a host service; there was no
gate to open. What was missing was the ERGONOMICS, which is what turned a
supported capability into something callers reached around the umbrella to get.

Three additive pieces, no gate touched:

1. LogosModuleContext::moduleName() — the module's own registry name, i.e. the
   origin it authenticates as. The typed wrappers bake their origin in at
   codegen time; a by-name call has to state one, and a wrong origin
   authenticates as nobody and fails far from the call site. Set through a NEW
   `_logosCoreSetModuleName_`, deliberately not a fourth parameter on
   `_logosCoreSetContext_`: every generated provider calls that signature, so
   widening it would break each one until regenerated, for a value the
   generator knows statically. Set before the context, so moduleName() is live
   inside onContextReady().

2. LogosModules::dynamic(target) on the origin-bound umbrella — the untyped
   client, with the origin baked in exactly as the typed members' is, and
   cached per target because LpClient owns a connection. The typed members over
   metadata.json#dependencies stay the ordinary way to call another module;
   this is for the cases whose target is a runtime value (a proxy, a router).

3. LpClient::getMethods() over the already-exported lp_get_methods. Invoke
   without introspect is guessing — a caller that cannot ask what exists can
   only hardcode, and a wrong guess fails at runtime like a typo.

Verified: #default builds, and both checks pass (tests, generator-cli).
