v0.5.3

• README repositioning. Agent_Sudo is framed as an authorization, delegation, provenance, and verifiable-audit engine for AI agents — MCP is the adapter, not the identity.
• Public metadata aligned. The PyPI summary and the MCP Registry server.json description carry the same authorization/delegation/provenance/verifiable-audit positioning, so package indexes and crawlers surface consistent framing.
• Audit Explorer — audit list filters + origin column. agent-sudo audit list gains --since, --decision, --origin, --actor, --tool, --target, and --non-allow, plus a provenance origin column. Read-only; --json output shape unchanged.
• Audit Explorer — audit trace <token_id>. Token-first delegation lifecycle inspection: resolves a token by full id or unique prefix, joins its store metadata with audit references, and reports observed consumes/denials and the causes denial reasons cite, with a raw-reason fallback. Read-only.
• Compatibility. No breaking changes, no schema changes, no policy-behavior changes, no new runtime dependencies.
