Root cause: missing SPI_SET_PARAMS (CMD 0x0B) before flash_begin.
ROM bootloader defaults to 2MB flash size, silently truncating
writes to 16MB flash. Progress bar showed success but firmware
was corrupt.
Changes:
- Add spi_set_params() with 16MB geometry before flash_begin
- Add MD5 verification after write (SPI_FLASH_MD5, CMD 0x13)
- Add retry logic (3 attempts per block)
- Pad firmware to 4-byte boundary
- flash_end(reboot=false) then separate hard reset after MD5 check
- Pure Rust MD5 implementation (no external crate)

Firmware sends: "KO2: 0B+02->4C+00"
Parser expected: "KO0: trigger=2A mod=02 -> result=4C resmod=00"
Rewrote parse_ko_lines to match real format:
<trigger_hex>+<mod_hex>-><result_hex>+<mod_hex>
Also skips "KO 0 deleted" and "KOSET 1:OK" lines.
