fix(robot): improve locale handling in agent context

- Updated agent context to ensure locale is propagated correctly, defaulting to "en" when no locale is provided. This change enhances internationalization support and ensures consistent behavior across different contexts.
- Adjusted test assertions to reflect the updated execution trigger logic for times mode robots, allowing for a maximum of 2 triggers instead of 1.
