[CodeBuildder]

Context

Heal-plan generator queries memory store for past successful actions on matching fault fingerprints. Parent: #49.

Acceptance Criteria

• Heal-plan generator queries memory store for top-3 matching incident records before invoking OpenAI model
• Past records injected into OpenAI model prompt as context
• Generated plan includes based_on_N_past_incidents field
• Integration test: pre-seed memory store with matching incident → plan references it
