Dockerfile.mst2

# mega2 with the MST/2 snapshot surface, for the compose acceptance stacks.
#
# The build context is this repository alone: the shared codec is a registry
# dependency (see Cargo.toml), so no sibling checkout or extra build context is
# needed. The registry version (0.3) carries the MTP2 route walk and the
# spec-conformance zstd fixes.
