Add the corim module that generates and validates CoRIM (Concise Reference Integrity Manifest) documents for IGVM launch endorsements per draft-ietf-rats-corim-10. The crate produces CBOR-encoded, tag-501-wrapped CoRIM documents containing: - A reference-values triple with the launch measurement digest - A conditional-endorsement-series triple mapping the digest to an exact SVN (microsoft#6.552) Supported platforms (via IgvmPlatformType): - Intel TDX (SHA-384, mkey "MRTD") - AMD SEV-SNP (SHA-384, mkey "MEASUREMENT") - Microsoft VBS (SHA-256, mkey "MEASUREMENT") Key design decisions: - Self-contained CBOR builder using ciborium::Value (no full corim crate dependency) - Strict profile enforcement: profile URI required, exactly one CoMID, CES required, only exact SVN, tag-id verified via UUIDv5 - Profile URI: tag:microsoft.com,2026:igvm-launch-endorsement/v1 Signed-off-by: Ming-Wei Shih <mishih@microsoft.com>
