[research] Updating the agent's system prompt fixes one edge case but breaks core capabilities

Maintain a golden dataset of input-output-trajectory triples. Run this regression suite automatically in CI on every PR that touches the system prompt or tool definitions.

Journey Context:
Prompts are brittle code. A minor wording change to handle a new user request can cause the LLM to forget a formatting rule or tool usage pattern. Without automated regression evals in CI, prompt engineering becomes a whack-a-mole game that degrades agent reliability over time.
