PM3_CMD_DATA_SIZE went 512 -> 624 without a capabilities bump, so a new
client connects to old firmware and every oversized command dies at the
device's length check with no message.
Append max_cmd_data_size, bump to v9. The client now accepts an older
capabilities struct - it only ever grows by appending, so an older layout
is a prefix - and defaults the frame size for pre-v9 firmware.
SendCommandNG bounds by the device value instead of the compile time one.
Also zero init capabilities_t on the device, it leaked stack bytes.
Allocate EF_SOD parsing scratch buffers on the heap so macOS worker threads do not exceed their stack while reading protected travel documents.

chunked by PM3_CMD_DATA_SIZE. Identical today, but if the NG size moves the
chunk would be built oversized, truncated on the wire, and still announced
at full length in oldarg[1] - the client would copy past the valid bytes and
advance by the wrong stride. Bound the client's OLD download branch by the
same constant.
nkeys was a 6 bit field but the client chunked by what fits in a frame -
123 keys in segment mode. nkeys wrapped to 59 while memcpy copied all 123
and the loop advanced by 123, so 64 of every 123 keys were never tested
and never reported. Full key mode was unaffected, it chunks 30.
Give nkeys its own byte. MIFAREU3P_CHKKEY_HEADER goes 18 -> 19, costing
one byte of payload, and segment mode chunks 123 again
Payload layout changed: client and firmware must be updated together.
Thanks Claude!
The OLD frame size was tied to the NG one, but the bootloader only speaks
OLD - growing PM3_CMD_DATA_SIZE would silently change sizeof(PacketCommandOLD)
and break flashing against every deployed bootrom in both directions.
Pin the OLD structs to their own constant and use it on every OLD path:
reply_old and the OLD receive branch on both sides, the bootrom, and the
flasher's write_block/send_finish_write_cmd, which memcpy into a
PacketCommandOLD using the NG size.
No behaviour change - both constants are 512 and armsrc .text is
byte-identical before and after.
Added status option to CLI for checking WiFi connection state and IP address. Updated command timeout for join and DHCP wait.
