Ryan Malloy 0d6facb321 Add experimental I2C debugging and EEPROM analysis tools 
One-off diagnostic scripts from experiments 0xD7-0xDB investigating
the I2C BERR deadlock. Documents the systematic elimination of
software-only recovery approaches:

- i2c_host_test.py: Proved 0xA0 register writes cannot drive I2C bus
- i2c_register_test.py: Tested I2C register writability from host
- i2c_recovery_boot.py: Attempted I2C state machine recovery via boot
- eeprom_flash_a0.py: Host-side EEPROM flash attempt (failed)
- boot_ab_test.py / boot_test.py: EEPROM boot reliability testing
- a8_autoclear_test.py: BCM4500 command register auto-clear behavior
- addr_gateway_test.py: BCM3440 gateway address routing analysis
- stock_fw_compare.py / stock_fw_test.py: Stock vs custom fw analysis
