Detailed Description

Minimal abstract I2C interface consumed by MCP23017Driver.

Concrete implementations:

• WireI2C — wraps Arduino Wire (drivers/WireI2C.h)
• MockI2C — records writes for host-side unit tests (test/test_xpoint.cpp)

Supply your own subclass for non-Arduino platforms or hardware mocking.
