Detailed Description

Implementation of the PCAL95555 GPIO expander handler.

Implements all three layers defined in Pcal95555Handler.h:

1. HalI2cPcal95555Comm – CRTP I2C communication adapter
2. Pcal95555Handler – Main handler (init, GPIO ops, interrupts, factory)
3. Pcal95555GpioPin – Per-pin BaseGpio wrapper

All driver calls use the PascalCase API of the updated hf-pcal95555-driver (pcal95555::PCAL95555<I2cType>). Error handling follows the driver's error-flag model: individual methods return bool, with accumulated error flags available via GetErrorFlags().
