Pull request overview

Adds a driver-factory abstraction so LittlebotHardwareComponent can create (or be provided) a driver via an injectable factory, enabling easier mocking in unit tests.

Changes:

• Introduces ILittlebotDriverFactory and a concrete LittlebotDriverFactory implementation.
• Updates LittlebotHardwareComponent to use the factory to create the driver during on_configure().
• Organizes test mocks under test/mocks/ and updates test includes accordingly.
