docs(web): fix non-compiling doc examples; bump to v1.1.0

Coordinated framework release. Documentation-only code changes plus the shared
version bump (folds the never-tagged 1.0.1 contracts pin into 1.1.0).

- mw.Recover() -> mw.Recover(logger): web/mw/doc.go, web/server/doc.go,
  web/server/server.go.
- health.NewHandler(...) -> ....ServeHTTP (chi Get takes HandlerFunc): web/server/doc.go,
  web/doc.go, web/health/doc.go.
- go.mod: contracts, core -> v1.1.0 (via go get + go mod tidy).

Verified by compiling the example patterns against the real API. Badge -> v1.1.0.
