this.method() links an imported function of the same name instead of the class's own method #3034

What happens

Inside a class that has a method with the same name as an imported function (a common thin-wrapper pattern), this.find(...) links to the imported function, not to the class's own method.

// lib.ts
export function find(x: string): string { return x; }

// handler.ts
import { find } from './lib';

export class Handler {
  run(s: string): string {
    return this.find(s);      // should be Handler.find
  }

  private find(s: string): string {
    return find(s);           // the imported function, correctly
  }
}

• Expected: Handler.run calls Handler::find.
• Actual on main (60b0d7a): Handler.run calls lib.ts: find, with resolvedBy: import.

this. is an explicit receiver, so an import binding of the bare name should never satisfy it. codegraph's own source has 7 such sites; for example, ToolHandler calls this.findAllSymbols(...), which wraps the imported findAllSymbols, and this.groupDefinitions(...) is the same. Callers of the wrapper method are missing as a result, and the imported function shows callers it doesn't have.

Found by diffing codegraph's call edges against scip-typescript (the TypeScript compiler's references) on codegraph's own repo.
