Groundwork for HTTP OTA emulation (GP RAM over HTTP / SCP81): the server
now emulates the terminal side of Bearer Independent Protocol and redirects
the card's TCP channel to a locally configured target.
- new pysim_otaman_server/httpota.py: BER-TLV parser for proactive commands,
BipTerminal (per-channel TCP client with rx buffering, redirect target,
bounded event log) and TcpDumpServer (raw capture listener used to
calibrate the card's TLS ClientHello before the PSK platform exists)
- server.py: BIP commands 0x40-0x43 (+0x44) are handled in
_handle_proactive_chain with TR payloads matching the captured real
terminal traces (result first, Channel status with link-established bit,
Bearer description, Buffer size, Channel data/length); connection
failures return result 3A/00; names and decoders added for the proactive
log; /api/scp81/status, /log, /log-clear and /bip (start/stop dump mode)
- tests: TR byte vectors from the traces, TLV parsing, open/send/receive/
close flow over a local peer, dump listener; 123 Python tests pass
