fix(event-dispatcher): avoid reentrant RefCell panics

Two related "already borrowed" panics reachable from
AutoloadGenerator::dump() (which holds the local-repository,
installation-manager, and config RefCells for the duration of its own
statement, per the temporary-lifetime-extension pattern fixed
separately in create_project_command.rs):

- ensure_bin_dir_is_in_path called config.borrow_mut() to read
  "bin-dir", but Config::get only needs &self; use borrow() so it can
  coexist with an outer borrow instead of conflicting with it.
- make_autoloader's real body needed composer_handle.borrow_mut() plus
  the same local-repository/installation-manager RefCells the caller
  already holds mutably, which cannot be made reentrant-safe without a
  larger restructuring. Since all 3 call sites already discard its
  return value, and its only effect (registering a Composer-generated
  ClassLoader for autoloading during event-listener PHP execution) is
  unobservable in this port — there's no embedded PHP interpreter to
  register it into, and class_exists for user-defined classes is a
  hardcoded-false shim so the caller's very next check always treats
  the class as unavailable regardless — make it a genuine no-op.

This unblocks the post-autoload-dump event for any script listener
naming a PHP class (e.g. Illuminate\Foundation\ComposerScripts), which
every create-project/install run reaches once real packages get
installed.
