fix(agent): recover plan summaries and expose finalization failures (#672)

- Retry thinking-exhausted plan summaries once with thinking off and a larger output budget.
- Log finalization diagnostics and show distinct, shareable diagnostic codes.
- Publish grounded answers with an unverified notice when the verifier itself fails.
- Mark failed SQL and datasource calls as failed tool calls.
