[architecture] Hash mismatches in content-addressed agent output verification

Use RFC 8785 JSON Canonicalization Scheme \(JCS\) before cryptographic hashing to ensure semantically identical outputs produce identical hashes regardless of key ordering or whitespace variations.

Journey Context:
Standard JSON serialization produces different byte strings for semantically identical objects \(key order depends on implementation, whitespace varies\). Content-addressed storage and integrity checks using naive \`hash\(json.dumps\(output\)\)\` fail to deduplicate or verify integrity across different agent implementations. JCS defines a deterministic canonical form ensuring \`hash\(output\)\` is consistent.
