0.2.0: Response grading, encrypted API keys, and quality-aware routing

Highlights of this release:

• LLM grading: optional LLM-as-a-judge scoring of every response, with results stored on the request log and visible in the backend module
• aim:grade-pending scheduler command as a safety-net for the live shutdown-handler grading path
• Grade-aware smart routing: cheaper models are only chosen if their graded quality is good enough
• API key encryption at rest using $TYPO3_CONF_VARS[SYS][encryptionKey]; endpoint URLs (Ollama, LM Studio) stay plaintext
• aim:rotateApiKeys command to re-encrypt stored keys after a SYS/encryptionKey rotation
• Install Tool upgrade wizard to migrate legacy plaintext API keys
• aim:test CLI command for one-off requests across all capabilities; --site resolves the provider from a site's settings.yaml
• Per-request privacy level override and metadata enrichment on AiRequestInterface
• Live model discovery for Symfony AI bridges with dynamic catalogs (Ollama, LM Studio)
• Streaming fix: stop dropping TextDelta chunks from the Symfony AI bridge (!2)
• Token-limit parameter resolved dynamically per bridge (fixes Gemini and others that expect a different key)
• Backend module hidden from non-admin users (!17)
• Symfony AI bridge dependency updated; declares a conflict with <0.8
