Pico FIDO - Token2 Hardware PIN Complexity Fork

This is a fork of Pico FIDO with hardware-enforced PIN complexity designed and tested for Token2 open hardware devices.

PIN complexity validation is enforced directly on the microcontroller during PIN setup, preventing weak credentials from being set regardless of client software.

Changes from Original

• Hardware-enforced PIN complexity - PIN complexity validation enforced at the firmware level, preventing weak credentials from being set regardless of client software
• LED behavior - Modified LED status indicators from the original implementation
• VID/PID - Uses Token2's official USB identifiers instead of the generic dummy VID/PID
• AAGUID - Modified to match a real authenticator identifier (self-attestation only, no external attestation at this time)
