[synthesis] Agent leaks memory via unbounded context growth in pagination loops

Implement streaming pagination: extract only needed fields per page, aggregate externally, keep only running summary in context

Journey Context:
When processing paginated data \(e.g., 'list all repos'\), agents often keep full JSON of page 1, page 2, etc. in context while requesting page 3. This linear growth quickly hits context limits or causes truncation of more recent/important data. The agent doesn't realize old pages are no longer needed for final aggregation and lacks the mechanism to compress historical pages into running totals. Standard 'keep last N tokens' truncation destroys the accumulated state. The solution requires treating the context as a streaming reduction pipeline rather than a historical log.
