CI / Release Workflows

.github/workflows/:

ci.yml: text-only changes skip; otherwise cargo test --workspace --locked on ubuntu-latest with protobuf compiler. OpenAPI-drift check that auto-commits the regenerated openapi.json for same-repo PRs. Also runs the AGENTS.md cross-link integrity check (scripts/check-agents-md.sh).
AWS feature build job: cargo build/test -p omnigraph-server --features aws on ubuntu-latest.
RustFS S3 integration: spins up RustFS in Docker, runs s3_storage, server_opens_s3_repo_directly_and_serves_snapshot_and_read, and local_cli_s3_end_to_end_init_load_read_flow.
release-edge.yml: on every push to main, retags edge, builds Linux/macOS-Intel/macOS-arm64 archives + sha256, publishes a rolling prerelease.
release.yml: on v* tags, builds the 3-platform matrix and updates the Homebrew tap (scripts/update-homebrew-formula.sh) by pushing the regenerated formula to ModernRelay/homebrew-tap.
package.yml: manual ECR image build; emits two image tags per commit (<sha>, <sha>-aws) via CodeBuild.
