Replace static hardcoded fallback list with the same robust approach used
by the opencode_local adapter: runChildProcess + ensurePathInEnv, HOME fix
via os.userInfo(), 60s TTL cache, returns [] on failure instead of a stale
list. Also updates CLAUDE.md and README.md with missing fields/features.

Surfaces the serviceAccountName field in the adapter UI under the
Kubernetes group. The job manifest builder already reads this field;
this change makes it configurable via the UI.
