`SessionSummaryManager` now exposes `last_n_runs` and `conversation_limit` parameters, giving precise control over how much of the conversation history is fed into summary generation. Teams running long sessions or high-frequency agents can use these to keep summaries focused and cost-efficient by limiting the input window rather than always summarizing the full history.

Details:

- `last_n_runs` limits summary generation to the most recent N runs in the session
- `conversation_limit` caps the number of conversation turns included in the summary input
- Both parameters work independently and can be combined
- No changes required for existing `SessionSummaryManager` configurations; defaults preserve current behavior
