[frontier] Returning massive JSON payloads from tools exhausts the context window and blows costs

Implement Tool Output Trimming and Summarization in the orchestration layer. Truncate large outputs or use a fast, cheap model to summarize the tool output into a few sentences before passing it back to the main agent.

Journey Context:
Agents often call cat on a huge file or get a massive JSON response from an API. Naively passing this to the LLM fails or costs a fortune in token processing. The orchestrator must act as a filter. The tradeoff is potential loss of granular detail, but an agent cannot reason effectively over 100k tokens of noise anyway.
