Jira LivenessProbe stub per ADR-021 §6.
Both Jira Cloud (API v3) and Self-Hosted/DC (API v2) expose
GET /rest/api/{2,3}/myself for the authenticated user.
Routing the response into the typed liveness shape requires
handling both flavours and the email+token vs PAT auth modes.
The stub uses the trait’s default test impl (returns
LivenessStatus::NotImplemented) until a real probe lands.
