✨ feat(lsp_completion): complete object creation and members

- Add class-name completion for `new` and `createobject("..."`.
- Generate constructor parameter snippets in completionItem/resolve.
- Support `obj.` instance member completion (methods/properties/fields).
- Infer `new`/`createobject` result types in SemanticModel TypeSystem.
