Create Evlog Framework Integration

This generates the boilerplate for adding a new framework integration to evlog, a structured logging library. You get two paths: manifest mode for standard request/response middleware frameworks like Hono or Express (about 30 lines of glue code), or custom mode for frameworks with weird lifecycles like NestJS or SvelteKit. The manifest approach uses defineFrameworkIntegration and covers roughly 80% of cases, while custom mode drops down to createMiddlewareLogger when you need more control. If you're maintaining evlog or want to add support for your preferred web framework, this scaffolds the integration pattern with reference implementations already in the repo.
