Tanmay Jain 014f8d1bbe FEAT(provenance): Add SLSA provenance attestation and verification (#13667)
* feat(provenance): add SLSA provenance and attestation signing libraries

Add internal/provenance for deriving in-toto subjects from Packer
artifacts, building SLSA Provenance v1 predicates, wrapping in-toto
statements, and best-effort git/CI source detection.

Add internal/attestation for DSSE envelope handling and a pluggable
Signer/Verifier backend supporting key (local PEM), kms (aws/gcp/
azure/hashivault), and keyless (Sigstore Fulcio) modes, plus Sigstore
bundle handling and DSSE/policy verification.

Add the supporting module dependencies in go.mod/go.sum.

* feat(provenance): add provenance post-processor

Add the opt-in "provenance" post-processor that runs after a build,
derives subjects from the artifact, emits DSSE-wrapped SLSA provenance
(and optional SBOM) attestations, signs them via the configured
signing backend, and writes sidecar files (including *.sigstore.json
bundles in keyless mode). Register it in the core post-processor set.

The provenance enable flag is a tri-state so an unset value stays
enabled through HCL2 decoding instead of being silently disabled.

* feat(provenance): add verify-attestation command

Add "packer verify-attestation" to verify signed DSSE attestations
against key, KMS, and keyless policy inputs, including optional
Sigstore bundle checks for Rekor and timestamp evidence. Register the
command in the CLI.

* docs(provenance): add reference CI workflows and changelog

Add reference GitHub Actions workflows under examples/ci for SLSA L2
keyless signing and L3-compatible delegated signing

* fix: lint and tests

* Added docs for Provenance PostProcessor
