From the JSonTypeInfo Javadocs:
> If deduction is being used annotation properties visible, property and include are ignored.
This is causing issues with serialization downstream.
- Replace McpError with appropriate standard exceptions (IllegalArgumentException, IllegalStateException) for validation errors
- Change tool/prompt registration to replace existing items instead of rejecting duplicates with warningsi
- Change addTool behavior to replace existing tools instead of throwing errors
- Change addPrompt() to allow replacing existing prompts with warning instead of throwing error
- Make removal operations idempotent - log warnings instead of throwing errors for non-existent items
- Change removePrompt() to log warning instead of throwing error for non-existent prompts
- Change removeTool() to gracefully handle non-existent tools with warnings instead of errors
- Add listTools() and listPrompts() methods to all server variants (async, sync, stateless)
- Add listTools() method to all server classes for tool enumeration
- Add listPrompts() method to all server implementations for retrieving registered prompts
- Improve error construction using McpError.builder() pattern for protocol-specific errors
- Update error handling in session classes to properly propagate McpError JSON-RPC errors
- Use proper error codes (INVALID_PARAMS) for prompt not found scenarios
- Update tests to reflect new lenient behavior for duplicate registrations and removals
- Add aggregateExceptionMessages() utility method utility to aggregate the exception chains
- Update McpServerSession and McpStreamableServerSession to use the aggregated errors in the json-rpc-error data section
This change makes the MCP server APIs more resilient and user-friendly by using appropriate exception types,
supporting item replacement, and providing listing capabilities while maintaining backward compatibility.

- Provide separation of concerns between static resources and parameterized resource templates.
- Add AsyncResourceTemplateSpecification and SyncResourceTemplateSpecification for both McpServerFeatures and McpStatelessServerFeatures
- Change resource template storage from List to Map to acomodate the resource read handler.
- Add runtime management methods: addResourceTemplate(), removeResourceTemplate(), listResourceTemplates()
- Improve error handling by using IllegalArgumentException/IllegalStateException instead of McpError
- Add new interfaces (Meta, Identifier) and reorganize schema hierarchy
- Enhance completion request validation with better error messages
- Add ResourceTemplate.Builder for easier template construction
- Update all server implementations (Async, Sync, Stateless) consistently
- Add type-safe constants for reference types (PromptReference.TYPE, ResourceReference.TYPE)
- Add tests for new resource template management functionality
- Clean up imports and remove unused dependencies

see: https://modelcontextprotocol.io/specification/2025-06-18/server/resources#error-handling
Resource not found should send a JSON RPC response such as:
```json
{
"jsonrpc": "2.0",
"id": 5,
"error": {
"code": -32002,
"message": "Resource not found",
"data": {
"uri": "file:///nonexistent.txt"
}
}
}
```
This PR also changes some instances where a `McpError` was thrown instead of being passed in the reactive chain with `Mono.error`
functional style
- Set MCP_2025_06_18 as upper supported protocol version for streamable-http and stateless transport
- Update LATEST_PROTOCOL_VERSION constant to reflect new upper bound
- Update test expectations for new protocol version usage

- Replace @ValueSource with @MethodSource for parameterized tests
- Add clientsForTesting() methods to provide test arguments consistently
- Remove hardcoded Spring-related labels from framework-agnostic mcp-test module
- Move mcp-test's utility classes from io.modelcontextprotocol.utils to io.modelcontextprotocol.util

* extract mcp-core
- This change extracts classes previously in `mcp` to `mcp-core`; a new module which does not depend on `mcp-json-jackon2`.
- `mcp` module is now an umbrella module that brings `mcp-json-jackon2` and `mcp-core`
* add mcp-core to bom
BREAKING CHANGE: All source code in the previously `mcp` module is moved to the `mcp-core`. the `mcp` now is just an aggregation for `mcp-core` + `mcp-json-jackson2` for backward compatibility.
This change won't affect the end users, but will cause conflicts for the existing PRs.
