catarrh e09aac4cb7 Add session export to PCAP
pcap.py: build_pcap(packets) — build PCAP bytes in memory (same format
as PcapWriter)
database.py: get_messages_raw() — raw elapsed/type/data without decode
server.py: GET /api/sessions/<id>/pcap generates a GSMTAP-encapsulated
PCAP (ATR/TPDU) with real timestamps and downloads it as
<session-name>.pcap (ASCII filename fallback + RFC 5987 UTF-8 for
spaces/unicode via _content_disposition)

tests: build_pcap + _content_disposition (67 total)

catarrh 73b0277ef7 Initial commit: simtrace2-pysniff v0.1.0
Python-based SIMtrace2 sniffer — drop-in replacement for simtrace2-sniff.
Single dependency (pyusb), auto-reconnect, GSMTAP/PCAP output, library API.

Modules:
  protocol.py — SIMtrace2 USB sniffing protocol parser
  device.py   — USB discovery + SniffSession with exponential backoff reconnect
  gsmtap.py   — GSMTAP UDP sender for Wireshark
  pcap.py     — PCAP file writer (LINKTYPE_GSMTAP)
  dump.py     — hex dump formatters + file output
  __main__.py — CLI entry point

Startup script sniff-start.sh handles udev permission checks and shows
install instructions. udev rule uses TAG+=uaccess (systemd-logind ACL).
