feat: enrich launch diagnostics and classify near-target health

[papi-ux]

Summary

• enrich game-detail Heads Up diagnostics with launch-profile provenance and structured health evidence
• classify HEALTHY only when grade, strict finite profile/telemetry evidence, target association, pacing, lifecycle, issue agreement, and all risk fields agree
• keep trial, recovery, learning, manual, upgrade, downshifted, missing, and unknown states fail-closed as warnings
• render finite-only diagnostic history and use semantic nova_success only for healthy state
• keep compact first paint while exposing expandable details
• wire deterministic controller focus: Play Up → More details, More details Down → Play

The initial lint/unit run hit the unrelated timing-sensitive NovaUpdateRecoveryTest.cancellationAfterAtomicCommitDeletesFinalArtifact. The exact test passed 10/10 fresh local repetitions, the complete x86_64 JVM lane passed, and the unchanged-SHA failed-job rerun passed.

Scope

• Nova client only
• no Polaris deployment, service restart, release, merge, game launch, or stream launch
