One git tag `harmony-fleet-operator-v*` now produces both the
container image and a hydrated helm chart at the same version,
pushed to hub.nationtech.io. release.sh is a 5-line wrapper around a
new `harmony-fleet-operator-release` binary in harmony-fleet-deploy
that orchestrates docker build/push, chart hydration via the
existing `build_chart()`, and `helm package`/`helm push`. CI is
reduced to a thin trigger calling the same script developers run
locally.
- chart.rs: ChartOptions gains an optional chart_version (None
preserves the previous CARGO_PKG_VERSION behavior).
- operator_release.rs: new binary.
- release.sh: thin wrapper.
- .gitea/workflows/harmony-fleet-operator.yaml: rewritten to fire
on `harmony-fleet-operator-v*` tags (and workflow_dispatch with a
manual version input).
