Output format instructions should not be included until the very last advisor runs, otherwise there's a risk of templating failure if more than one advisor tries to render the prompt template. This change guarantees the output format instructions are always included right before calling the chat model, without the risk of previous advisors interfering with it.

- Move evaluation core classes (Request, Response, Evaluator) to spring-ai-commons.
- Move chat-specific evaluators (FactChecking, Relevancy) to spring-ai-client-chat#evaluation package.
- Move OutputConverter implementations and related classes to spring-ai-model#converter package.
- Move MetadataEnricher transformer classes to spring-ai-model#transformer package.
- Move PromptAssert utility to spring-ai-rag#util package.
- Update relevant pom.xml files and adjust imports in affected classes.
- Document class movements in upgrade-notes.adoc for M8 release.
This refactoring improves module organization and separation of concerns.

Renames the ambiguous overloaded `tools` methods in `ChatClient.PromptRequestSpec`
to `toolNames` and `toolCallbacks` respectively. This improves clarity
and prevents potential issues with method dispatching based on argument types.
Updates relevant code examples and adds documentation to upgrade notes.

- Extend the ChatClient with a new templateRenderer() method to pass a custom TemplateRenderer object used to render user and system templates.
- Evolve the QuestionAnswerAdvisor to accept a PromptTemplate for customising the RAG prompt and templating logic while maintaining backward compatibility.
- Introduce integration tests for the QuestionAnswerAdvisor.
- Document the TemplateRenderer API and how to use it to build PromptTemplate with custom templating logic.
- Document how to customise the templating logic used internally by the ChatClient via the TemplateRendererAPI.
Add validation tests and improve PromptTemplate resource handling
Enhance robustness and reliability of the PromptTemplate class with better
resource handling and comprehensive input validation:
- Add dedicated validation tests for builder methods with null/invalid inputs
- Improve renderResource method to gracefully handle edge cases:
- Null resources return empty string
- ByteArrayResource handling with proper charset (UTF-8)
- Empty resources check with proper existence test
- Better error handling with logging instead of exception propagation
- Add input validation assertions to all Builder methods
- Fix typo in deprecated annotation comment ("fahvor" → "favor")
Update documentation to clarify template rendering in different contexts:
- Add clear notes about TemplateRenderer usage in ChatClient vs Advisors
- Document how advisor template customization differs from ChatClient template rendering
- Add comprehensive API upgrade notes for template-related deprecations
- Include detailed migration examples for PromptTemplate and QuestionAnswerAdvisor

* ChatClient observations now include the full prompt content instead of just the userText and systemText. Furthermore, they include consistent telemetry for the tools passed via the ChatClient and a first-class conversation ID when using memory advisors. Incomplete or unsafe attributes have been deprecated.
* Adopted the new robust Advisor APIs for BaseAdvisor and RetrievalAugmentationAdvisor.
* Improved the prompt augmentation facilities in ChatClientRequest and Prompt for performance and immutability.
* Fixed integration test racing condition.
* Updated the documentation for ChatClient and Observability accordingly.
* Documented changes in upgrade notes.
* Introduced `prompt.augmentUserMessage(String text)` to directly replace the user message content.
* Added `prompt.augmentUserMessage(Function<UserMessage, UserMessage> augmenter)` for more granular updates using the `userMessage.mutate()` pattern, allowing modification of text, media, and metadata.

* ChatMemory will become a generic interface to implement different memory management strategies. It’s been moved from the “”spring-ai-client-chat” package to “spring-ai-model” package while retaining the same package, so it’s transparent to users.
* A MessageWindowChatMemory has been introduced to provide support for a chat memory that keeps at most N messages in the memory.
* A ChatMemoryRepository interface has been introduced to support different storage strategies for the chat memory. It’s meant to be used as part of a ChatMemory implementation. This is different than before, where the storage-specific implementation was directly tied to the ChatMemory. This design is familiar to Spring users since it’s used already in the ecosystem. The goal was to use a programming model similar to Spring Session and Spring Data.
* The JdbcChatMemory has been supersed by JdbcChatMemoryRepository.
* A ChatMemory bean is auto-configured for you whenever using one of the Spring AI Model starters. By default, it uses the MessageWindowChatMemory implementation and stores the conversation history in memory. If a different repository is already configured (e.g., Cassandra, JDBC, or Neo4j), Spring AI will use that instead.
* First-class documentation has been introduced to describe the ChatMemory API and related features.
* All the changes introduced in this PR are backward-compatible.

- Introduce “ChatClientRequest” and “ChatClientResponse” for propagating requests/responses in a ChatClient advisor chain.
- Structure a Prompt at the beginning of the chain, to ensure a consistent view across execution chain and observations. Any template is rendered at the beginning so that every advisor doesn’t have to do it again.
- Improve observations to include the complete view of the prompt messages, instead of only considering userText and systemText.
- Remove legacy “around” advisor type concept.
- Keep backward compatibility for AdvisedRequest, AdvisedResponse, and legacy Advisor APIs.
