BridgeJS: Include properties and release() in declare global class stubs

[krodak]

Overview

When exposeToGlobal: true is set in bridge-js.config.json, BridgeJS emits a declare global block so TypeScript knows the exported Swift classes exist on globalThis. These stubs were generated with constructor signatures and methods, but two things were always missing:

• Instance properties (@JS var declarations on the class)
• release(): void (inherited from SwiftHeapObject by every exported class)

This meant that accessing an instance through the globalThis path produced a TypeScript type with no properties and no release(), forcing consumers to use as unknown as TheInterface casts to recover full typing.

Before (declare global stub for a class with a precision property):

declare global {
    namespace Utils {
        class Converter {
            constructor();
            toString(value: number): string;
            // precision: number  ← missing
            // release(): void    ← missing
        }
    }
}

After:

declare global {
    namespace Utils {
        class Converter {
            constructor();
            toString(value: number): string;
            precision: number;
            release(): void;
        }
    }
}

The fix is a small addition to generateNamespaceDeclarationsForNode in BridgeJSLink.swift: after emitting methods, emit non-static properties sorted by name, then always append release(): void.

Three snapshot files are updated: Namespaces.Global.d.ts, EnumNamespace.Global.d.ts, and MixedModules.d.ts.
