- Provide separation of concerns between static resources and parameterized resource templates.
- Add AsyncResourceTemplateSpecification and SyncResourceTemplateSpecification for both McpServerFeatures and McpStatelessServerFeatures

- 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

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

* 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.
