feat(refactor): Java Pull Members Up / Push Members Down (#1183)

Refactor | Pull Members Up… and Push Members Down… for Java, from the Refactor menu, the editor context menu and Refactor This. A dialog picks the destination and the members (Make abstract / Keep abstract); problems are confirmed before anything changes; the edit is applied as one change or previewed first.

JDT LS offers neither as a code action, so the app-owned JDT LS bundle (plugins/java-usages 1.3.0) adds two delegate commands that run JDT's PullUpRefactoringProcessor / PushDownRefactoringProcessor and return the problems and the edit without applying it, exposed as lsp_hierarchy_members / lsp_hierarchy_refactor (also over the remote host dispatcher). The bundled jar was rebuilt from source with JDT LS 1.63.0 and matches the recorded SHA-256.
