<issue_title>[lsp] Go to Definition missing getter when property returns callable interface</issue_title>
<issue_description>## VS Code Editor Issue

Extension Version: 0.20251203.1
VS Code Version: 1.106.3
Operating System: Windows 11 Pro 24H2 (Build 26100.7171)

Steps to Reproduce

1. Create two files as shown below (or clone the minimal reproduction repository)
2. Open VS Code with TypeScript Go Native enabled
3. Openindex.ts
4. Place cursor ononDidChangeContent in line 5:documents!.onDidChangeContent()
5. Execute "Go to Definition" (F12)

index.ts

import{TextDocuments}from"./type";vardocuments:TextDocuments;documents!.onDidChangeContent()//         ^ Go to Definition here

type.d.ts

exportinterfaceEvent{():any;}exportdeclareclassTextDocuments{getonDidChangeContent():Event;}

Minimal reproduction repository:https://github.com/imbant/ts-go-definition-bug

Issue

Expected Behavior (Strada / JS Language Server)

Returns2 definition locations:

1. interface Event callable signature (line 2 intype.d.ts)
2. get onDidChangeContent() getter definition (line 6 intype.d.ts)

Actual Behavior (TypeScript Go Native)

Returns only1 definition location:

1. interface Event callable signature

❌Missing: The getterget onDidChangeContent(): Event definition

Analysis

The propertyonDidChangeContent is agetter that returns acallable interface (Event). When the code isdocuments!.onDidChangeContent():

• onDidChangeContent accesses the getter
• () invokes the callable interface returned by the getter

"Go to Definition" should return both:

1. The callable interface signature being invoked
2. The getter property that provides this value</issue_description>

<agent_instructions>index.ts contains:

import{TextDocument,TextDocuments}from"./type";vardocuments:TextDocuments<TextDocument>;documents!.onDidChangeContent()

types.d.ts contains

exportinterfaceDisposable{/**   * Dispose this object.   */dispose():void;}exportinterfaceEvent<T>{/**   *   *@param listener The listener function will be called when the event happens.   *@param thisArgs The 'this' which will be used when calling the event listener.   *@param disposables An array to which a {{IDisposable}} will be added.   *@return   */(listener:(e:T)=>any,thisArgs?:any,disposables?:Disposable[]):Disposable;}exportinterfaceTextDocumentChangeEvent<T>{/**   * The document that has changed.   */document:T;}exportdeclareclassTextDocuments<Textends{uri:string;}>{getonDidChangeContent():Event<TextDocumentChangeEvent<T>>;}exportinterfaceTextDocument{uri:string;}

Create a fourslash test for this first, then work on the issue</agent_instructions>
