Fix dropped change flags + FIDI parsing
- capture.py: DirectSniffer/GsmtapListener yield (type, data, flags),
CaptureManager passes flags to insert_message (change flags were
previously dropped, leaving every change row with flags=0)
- protocol.py: add _parse_fidi (1-byte value) — FIDI was mis-mapped to
_parse_change (4-byte flags), so FIDI messages were silently dropped
- database.py: pass flags into decode_sniff_msg
- decode.py: decode_change(flags) reads flags directly; decode_sniff_msg
gains flags parameter; change messages no longer require non-empty data
- tests: fix FIDI test, add change/fidi decode tests (43 total)

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).
