Ryan Malloy 3d2cd477b2 Add EEPROM boot firmware (exp 0xDB) and supporting tools 
Firmware: Rewrite skywalker1.c for EEPROM boot experiment — tests
whether I2C hardware controller works after FX2 boot ROM completes
EEPROM load (bypassing the CPUCS restart that triggers BERR).

Tools:
- fw_load.py: Add I2C cleanup stub, pre-halt register flush, improved
  error handling and segment loading
- eeprom_write.py: Add IHX→C2 EEPROM image converter (16KB format
  with length-prefixed segments, checksum)
- eeprom_dump.py: Refactor for cleaner output, better hex display
- skywalker_lib.py: Minor I2C register constant updates

Docs:
- EEPROM-RECOVERY.md: Four recovery options for soft-bricked device
  (SOIC clip, SDA pull-up, desolder, wait-for-timeout)
- Master reference: Updated with EEPROM boot findings

Status: EEPROM flash blocked — stock firmware I2C proxy returns pipe
errors, host-side 0xA0 writes proven unable to drive peripheral bus.
Device boot ROM intermittently hangs on EEPROM I2C read (~3-6% success).
