[synthesis] Agent repeatedly uses a single tool even when it's returning no results, instead of switching to a different tool or strategy

Implement a 'tool fatigue' counter or explicitly prompt the agent to switch strategies if a tool returns empty results N times consecutively.

Journey Context:
Agents often get stuck in a 'hammer and nail' loop. If grep returns nothing, the agent assumes the query is slightly wrong and tries variations, rather than realizing the file doesn't exist or using find. The root cause is that the LLM's attention is focused on the tool's output format, not the meta-strategy. By injecting an observation like 'Tool X has returned empty 3 times. Try a different approach or tool,' you break the local search and force global exploration.
