feat(event-dispatcher): run composer.json PHP scripts through the RPC worker

Implement the two script execution paths that previously stopped at
todo!(): a Class::method listener is invoked as CallStaticMethod with the
event crossing the boundary as a proxy-stub handle, and a Command-class
listener runs inside a throwaway bare Symfony Application hosted by the
worker via a generated snippet, its BufferedOutput written back through
the dispatcher's IO. makeAutoloader is ported for real (canonical-package
hash, setDevMode, buildPackageMap/parseAutoloads/createLoader), and the
class_exists/is_callable/is_a/defined guards now query the worker, whose
script autoloader resolves classes by asking the Rust-side ClassLoader
over the reverse channel. EventInterface gains as_any (the IOInterface
downcast pattern) so the concrete event type is reachable behind the
trait object. Application::do_run now registers ScriptAliasCommand
entries as typed commands, unblocking the run-script --list/alias tests;
the dev-mode-to-generator test is ported with local mockall mocks. The
remaining ignored tests carry re-verified reasons: the listener methods
live on the PHPUnit test class itself (unloadable in the worker), or the
test needs live import of a user PHP Command class into the Application.
