2e00a054e8 Add comparative firmware analysis reports from Ghidra 8051 reverse engineering 
Two detailed reports from analyzing all firmware variants loaded into Ghidra:

1. v2.06 vs v2.13 FW1 comparative analysis:
   - Complete vendor command dispatch table mapping (0x80-0x9D)
   - 3 new commands in v2.13: GET_DEMOD_STATUS (0x99), INIT_DEMOD (0x9A), DELAY_COMMAND (0x9C)
   - DiSEqC architecture change: GPIO bit-bang -> I2C controller
   - INT0 repurposed from USB re-enumeration to demodulator polling
   - Hardware revision detection via descriptor byte

2. v2.13 sub-variant comparison (FW1/FW2/FW3):
   - FW1: I2C-connected demodulator (original SkyWalker-1 hardware)
   - FW2: Parallel-bus demodulator via P0/P1 GPIO
   - FW3: Enhanced parallel-bus with dual-phase read and OR accumulation
   - All three support identical modulation types, differ only in hardware interface
