docs(core): fix logz.Options -> logz.Config in doc examples; bump to v1.1.0

Coordinated framework release. Documentation-only code change plus the shared
version bump.

- core/launcher/doc.go, core/logz/doc.go: logz.New(logz.Options{...}) ->
  logz.Config (Options was retired per ADR-003; the constructor takes Config).
- go.mod: contracts -> v1.1.0 (via go get + go mod tidy).

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

+
+Coordinated framework release. Documentation fix plus the framework version bump.
+
+### Fixed
+
+- **Package doc examples referenced the retired `logz.Options`.** `logz.New` takes
+  `logz.Config`; the `launcher` and `logz` package docs showed `logz.New(logz.Options{…})`,
+  which does not compile. Both corrected to `logz.Config`, verified by compiling the example
+  patterns against the real API.
+
+### Changed
+
+- Bumped `contracts` to v1.1.0 (framework version alignment).
