feat(dependency-resolver): wire operation get_package and unblock solver tests

Override OperationInterface::get_package for Install/Uninstall/MarkAlias*
operations so trait-object dispatch no longer hits the default todo!(), and
implement Rule::is_caused_by_lock's locked-repository lookup via
Request::get_locked_repository (LockArrayRepository::get_packages is infallible).

Change PackageInterface::get_type to return String (matching PHP getType():
string) so AliasPackage can delegate live to its aliasOf handle across the
RefCell instead of an impossible &str borrow.

Un-ignores 25 SolverTest cases; 2 alias cases stay ignored pending a real
solver alias-resolution discrepancy.
