Weather tool handles country-only location

A smoke test was added for the weather tool to verify it resolves ‘germany’ without error. This test complements a rewritten nightly scenario that ensures prompts for Berlin/Germany are routed to the weather tool, passing ‘germany’ in parameters. The nightly test asserts the ACT loop sends the prompt to the tool and supplies the country name. This new integration test specifically verifies that the tool successfully processes a country-only location string, utilizing the wttr.in fallback path since Open-Meteo requires coordinates that are not provided. The test is marked as integration and performs a real outbound HTTP call, taking approximately 1.5 seconds to run.
