A Windows user could run the bash launchers from WSL or Git Bash / MSYS2 /
MinGW / Cygwin, where the Linux USB assumptions do not hold: WSL cannot reach
the Windows SIMtrace2 device, and those shells have no Linux /sys + /dev/bus/usb
view for the udev pre-flight. Both launchers now detect a Windows host up
front (WSL via /proc/version, the rest via uname -s) and exit 2 with a pointer
at the matching .bat launcher, which drives the Windows Python/PyUSB stack.
The message goes to stderr; a deliberate WSL/Cygwin flow can still run the
Python module directly (noted in the source comment).
Tests: tests/test_launchers.py runs each script with a fake mingw uname and
asserts exit 2 plus the start.bat/sniff-start.bat pointer, pins the WSL
detection, and checks bash -n syntax (skipped when bash is absent).
Bumps 2.7.14 (version.py, pyproject, PWA_VERSION), SW cache v96, the README
download examples and the release-notes preamble. 561 Python + 80 Node tests.
dump.py: tpdu_timestamp_prefix(), tpdu_atr_time_prefix(),
format_message() accepts tpdu_prefix parameter,
FileDumper supports fmt + ATR time tracking
__main__.py: --format/-f flag (hex|timestamp|atr-time),
atr_time_start tracking in message loop
sniff-start.sh: pass through --format/-f and FORMAT env var
