refactor: extract snapshot_identity_bytes from compute_snapshot_id

compute_snapshot_id is now a thin wrapper over snapshot_identity_bytes, which returns the canonical payload whose sha256 equals the snapshot_id. Mirrors the commit_identity_bytes extraction done for Phase 1.

Tests: TestSnapshotIdentityBytes — seven cases covering importability, return type, sha256 round-trip, directories variant, order independence, field sensitivity, and empty manifest. Written red first.
