ci: install uv for the Python runtime test suite (#7)

The container-mode lifecycle test drives the Python runtime's Test step,
which runs `uv` on the host to sync dependencies and run pytest. The runner
doesn't ship uv, so `go test ./...` failed with `exec: "uv": executable file
not found in $PATH`. Install it via the shared workflow's setup-run hook.
