…s#24) Fixes flashbots#144 The cache key was `<package>-<git_describe>` — source identity only. Build-input changes (RUSTFLAGS, GOFLAGS, cargo profile env vars, toolchain version) silently reused cached binaries built under different conditions. Cache key is now `<package>-<git_describe>-<env_hash>`, where env_hash is `sha256(build_cmd || $MAKE_GIT_PACKAGE_CACHE_KEY_EXTRA)`. build_cmd is always hashed in. MAKE_GIT_PACKAGE_CACHE_KEY_EXTRA is opt-in for caller-injected inputs — e.g., the rust toolchain version installed via rustup, so that toolchain bumps invalidate cached binaries built under the previous one. Existing caches invalidate once when this lands.
