ClickUp LivenessProbe stub per ADR-021 §6.
ClickUp’s introspection endpoint is GET /api/v2/user, but
routing the response through the typed liveness shape (active /
revoked / expired) requires more sniffing than this commit’s
scope allows. The stub uses the trait’s default test impl
(which returns LivenessStatus::NotImplemented) and wires
the provider name so doctor shows
“clickup liveness probe is not implemented; format-only
validation only” instead of “no probe configured”.
Replacing the stub: drop a real test override against
<base>/api/v2/user, mirroring crates/plugins/api/github.
