feat(app): Add WebStorm editor target (#220)

* Add WebStorm editor target

* Fix rebase type errors and add TODO date tag

- Await listAvailableEditorTargets() which became async on main
- Wrap sendAgentMessage callback to match Promise<void> return type
- Add TODO(2026-07) date to legacy editor target ids comment
