[synthesis] Agent context window fills up and degrades after a single tool call returns overly comprehensive data

Cap the character limit of tool return payloads at the orchestrator level, forcing the tool to return a truncated summary with a fetch more mechanism, rather than returning raw giant strings.

Journey Context:
A common failure mode is an agent calling list\_files or read\_codebase and getting 50k tokens back. The agent then tries to reason over this massive context, leading to degraded reasoning and high latency. The synthesis is that tool design for agents is fundamentally different from tool design for humans. Human tools should be comprehensive; agent tools must be lazy and paginated by default to prevent context explosion.
