macp-runtime 0.8.4

MACP reference runtime: a coordination kernel and gRPC server enforcing session boundaries, message validation, append-only history, modes, and governance policy.
Documentation
# Runs the integration_tests crate (Tier 1 protocol, Tier 2 Rig tools, Tier 3
# real-LLM E2E -- see docs/testing.md) inside a container that builds the
# runtime binary from this checkout and drives it through the real gRPC
# boundary, exactly like ci.yml's `integration` job (MACP_TEST_BINARY
# subprocess mode). Tier 3 additionally needs OPENAI_API_KEY (picked up from
# a `.env` file at the repo root, gitignored, or the host environment).
#
# Usage:
#   docker compose build integration-tests
#   docker compose run --rm integration-tests                                          # tier 1 + tier2 (default CMD)
#   docker compose run --rm integration-tests cargo test --test tier3 -- --ignored --test-threads=1   # tier 3, real LLM
#   docker compose run --rm integration-tests cargo test -- --test-threads=1            # everything except #[ignore]d tier 3
