simple-someip 0.10.0

# vsomeip 3.4.10 + a minimal offerer that advertises service 0x1234
# instance 0x0001 via SD multicast. Used by the host-side
# conformance test in `tests/vsomeip_sd_compat.rs`.
#
# Build:
#   docker build -t vsomeip-offerer tests/data/vsomeip-offerer/
#
# Run (host network mode so SD multicast 224.0.23.0:30490 reaches the
# host's listener — required for the cargo test to receive the
# OfferService broadcast):
#   docker run --rm -d --name vsomeip-offerer --network host \
#       vsomeip-offerer
#
# Verify it's emitting:
#   docker logs vsomeip-offerer
#
# Stop:
#   docker stop vsomeip-offerer
#
# Pinning to vsomeip 3.4.10 specifically because that's the version
# LumPDK / EnVision use (see LumPDK/packages/thirdparty/vsomeip/
# vsomeip.MODULE.bazel). Keeping wire-version-aligned with production
# avoids interop quirks during CI conformance testing.
