This created invalid AST structures where a MethodDeclaration was a direct child of SourceFile (e.g., for methods in object literals). TypeScript's implementation keeps overload information in the JSDoc structure and retrieves it when needed by the checker/declaration emitter, rather than creating synthetic AST nodes that get added to reparseList. This fix removes the code that was creating these invalid synthetic nodes. The overload information remains in the JSDoc and can be accessed by future checker improvements.

Object literal methods are silently ignored to maintain compatibility with alternative @overload syntax. Also added nil check in checker.getConditionalFlowTypeOfType to prevent panic when synthetic overload nodes have nil parents. This restores function and class method overload support while preventing invalid AST structures from object literal methods. Addresses @jakebailey's feedback to make the fix more targeted.

Uses the PCObjectLiteralMembers parsing context flag to detect when we're parsing an object literal, allowing proper error reporting during the reparsing phase. Addresses @jakebailey's feedback to use the JSDoc error reporting mechanism.
