fix(examples): pin the release version instead of latest

[scttbnsn]

Six of the seven example files used ghcr.io/codeswhat/portwing:latest, so an example copied today would change behaviour under you at the next release. They now pin the release version, the same way the observability example already did.

• The four Compose examples and both Kubernetes manifests pin 0.9.25.
• The release contract checks all seven example files: each must carry the current release version and none may use latest for the Portwing image. The self-test mutates each file both ways.
• RELEASING.md lists the examples among the files the release prep bumps.

All five Compose examples still pass docker compose config -q. The Kubernetes manifests keep imagePullPolicy: Always.
