Free2PA 0.3.3 - Optional installable LLM auditors

Free2PA 0.3.3 separates deterministic trust from optional LLM behavioral review.\n\nHighlights:\n- Free2PA signing, verification, publisher trust, repair, CLI, MCP, and load gates run with no LLM account.\n- Operators can bring their own OpenAI, Azure OpenAI, or OpenAI-compatible account.\n- Other hosted or local LLMs can be installed through the FREE2PA_AUDITOR_MODULE provider contract.\n- New free2pa auditor status command makes the optional configuration visible.\n- Provider-neutral workbench labels retain provider and model evidence in results.\n- An LLM report cannot change REJECT to LOAD, admit a publisher, sign, or repair.\n- 18 automated tests pass and the clean dependency audit reports zero vulnerabilities.\n\nPackage SHA-256: 07f7a3e00c18cb342ea0bfd168af40fd8c436a84a4e2fdf1849d997d3e3e36c2\n\nFree2PA is C2PA-inspired and uses its own sidecar format; it does not claim C2PA conformance.
