Express Response End Event Middleware

The `express-end` package provides a specific Express middleware designed to augment the default event handling on the `res` (response) object. Its primary function is to emit an `end` event whenever `res.end()` is called, crucially, even if the client connection has closed prematurely. This addresses a common limitation where the standard `finish` event on the `res` object might not reliably fire under such circumstances, preventing middleware from consistently determining when server-side processing for a request has fully concluded. This capability is useful for tasks like consistent post-request logging, resource cleanup, or metric collection. The package is currently at version `0.0.8` and has not been updated since 2016, indicating it is an abandoned project. Its core differentiator is providing a consistent signal for server-side request completion, regardless of client connection status, a problem that might be solved differently or directly in modern Express versions.
