Subject: [PATCH] docs(smtp): fix fictional launcher.Register/health.Register
 in doc examples

The package-doc examples showed a fictional launcher.Register / health.Register
API (and launcher.Append as a package func). Corrected to the real wiring:
lc.Append + web/health.NewHandler(...).ServeHTTP.

Documentation-only. No code, API, or dependency changes; version stays v1.1.0
(the v1.1.0 tag is moved to include this fix). Verified by compiling the
corrected pattern against the real API.

 ```
 
 When `cfg.Host` is empty, `New` returns a no-op that logs every `Send` call at debug level and always returns nil. No code changes are needed between environments.
