session-retro

Run an interactive session retrospective. Reads the per-session event log (maintained by the PostToolUse hook) and uses git diff/status/log as memory primer, then walks through specific moments via adaptive questions driven by what changed, and writes structured native memory entries. Suggest this when a Stop or PreCompact hook has injected a /retro suggestion, or when the user explicitly asks for one. Triggers: "retro", "session summary", "what did we learn", "lessons learned", "session retrospective".
