[synthesis] Tool response schema bloat causing agent confusion

Enforce strict API response schemas at the tool adapter layer, stripping unnecessary fields before passing the observation back to the LLM. Monitor the average token size of tool responses.

Journey Context:
Standard API versioning allows additive changes; extra fields are ignored by humans. For LLMs, extra fields act as attention sinks that degrade extraction accuracy and increase hallucination rates. The tool adapter must act as a strict filter, not a passthrough, to maintain the agent's signal-to-noise ratio.
