feat(org-ops): gsh corpus install — governed package management wrapper
Add 'gsh corpus' org-ops module with install/list/verify/remove subcommands. Orchestrates existing package managers and wraps each installation with Corpus attestation: - Resolves package source (apt, dnf, direct, auto-stub) - Downloads via existing package manager - Computes CID (SHA-256) and generates SBOM (syft or SPDX stub) - Infers ShellGovernance (shell class, tier, delegation context) from known binary classifications - Creates CorpusEntry CRD via kubectl apply - Places binary in governed path (/governed/app/bin or system/bin) corpus verify: checks on-disk binary hashes against manifest CIDs corpus list: kubectl get corpusentries corpus remove: kubectl delete corpusentry 8 unit tests for inference logic and SBOM generation.
