[synthesis] Agent hallucinates API responses or tool outputs when hitting undocumented rate limits or timeouts

Enforce explicit error handling for HTTP 429/503 and timeout exceptions at the tool execution layer, returning a standardized wait-and-retry message to the LLM rather than letting the raw exception or empty response hit the context.

Journey Context:
When an agent hits a rate limit, the tool often returns an HTML error page, a 429 JSON, or an empty string. The LLM, trying to be helpful, will often try to parse this garbage as valid data, leading to completely hallucinated subsequent steps. Developers assume the LLM will see '429 Too Many Requests' and understand, but LLMs often lack the context to interpret raw HTTP errors correctly. The synthesis is that the translation of infrastructure errors into LLM-consumable directives must happen at the tool boundary.
