chore(logs): promote run lifecycle traces to info level

Promotes per-run observability events (stage start/complete, edge
selection, checkpoint, fidelity resolution, agent session, LLM stream
finish, tool calls, sandbox cleanup, PR build/create) from debug to
info so default-level operators see end-to-end run progress.
