Why?

CJS TypeScript users who write import Stripe = require('stripe') get no type information from StripeConstructor it's untyped, so new Stripe() and Stripe() both resolve to any. This makes the CJS TypeScript experience significantly worse than ESM, where full types are available.

What?

• Added a StripeCallableConstructor type to stripe.cjs.node.ts and stripe.cjs.worker.ts that intersects typeof Stripe (construct signature + static members) with a call signature.
• Now both new Stripe(key, config) and Stripe(key, config) are fully typed for CJS TypeScript consumers
• Added a new testProjects/cjs-ts/ integration test project that validates CJS TypeScript usage: constructor patterns, static member access, instance members, error handling, and instanceof checks
• Expanded the existing testProjects/cjs/index.js test to cover both callable and new patterns, static property access, and instanceof checks
