The Spring-specific transport modules (mcp-spring-webflux,
mcp-spring-webmvc) have been moved out of the MCP Java SDK into the
Spring AI project (org.springframework.ai group), effective with
MCP Java SDK 1.0 and Spring AI 2.0. This is a breaking change.
- Delete mcp-spring-webflux and mcp-spring-webmvc source modules
- Remove both artifacts from mcp-bom and root pom.xml module list
- Update docs and README
- Add blog post explaining the breaking change with before/after
migration examples
Resolves: #127

The initialize timeout was too short to be able to download the server
with NPX. As stated in the javadoc of `StdioMcpSyncClientTests`:
> These tests use npx to download and run the MCP "everything" server
> locally. The first test execution will download the everything server
> scripts and cache them locally, which can take more than 15 seconds.
> Subsequent test runs will use the cached version and execute faster.
Since the download happens on calling "connect", it is triggered during
the initialization of the client.

As a follow-up of #779, this commit refines McpJsonDefaults
method names by shortening them to not repeat the qualifiers
already expressed at type level.
- The integration tests pass with both Jackson 2 and Jackson 3.
- Modified McpSchemaTests.testContentDeserializationWrongType to work
with both Jackson 2 and Jackson 3.

This is a follow-up to #742.
The `mcp-test`, `mcp-spring-webflux`, and `mcp-spring-webmvc` depended
on `mcp` module which transitively brought in Jackson 3 dependencies.
These modules are now decoupled and only depend on `mcp-core`.
The test dependencies bring in Jackson 2 for the time being.
This is a breaking change but it is required to allow easily exchanging
Jackson2 and Jackson3 modules.

This change adds Jackson 3 support and aligns package naming in the existing Jackson 2 module.
Specific changes:
* Deprecated classes for removal in `io.modelcontextprotocol.json.jackson`/`io.modelcontextprotocol.json.schema.jackson`
* Copied the above to `io.modelcontextprotocol.json.jackson2`/`io.modelcontextprotocol.json.schema.jackson2` in non-deprecated form.
* Added tests for the default McpJsonMapper and JsonSchemaValidator
* Pin `npx @modelcontextprotocol/server-everything` version to `2025.12.18`.
* Replace `tzolov/mcp-everything-server` Docker image with `node:lts-alpine` + `npx` command.
* Handle HTTP 202 special case.
* Fix test assertions.
The recent rollout of everything-server broke integration tests which take the latest version from the node registry.
This PR unifies the everything-server usage - the Testcontainers Docker setup uses the same version as the STDIO npx-based tests and no longer relies on tzolov/mcp-everything-server.

Update the ClientCapabilities.Elicitation record to accept optional "form"
and "url" fields as defined in the MCP 2025-11-25 specification.
Previously, deserializing an InitializeRequest with
`{"capabilities":{"elicitation":{"form":{}}}}` would fail with
UnrecognizedPropertyException because the Elicitation record was empty.
Changes:
- Add nested Form and Url marker records to Elicitation
- Add no-arg constructor for backward compatibility (serializes to {})
- Add elicitation(boolean form, boolean url) builder method
- Add comprehensive tests for deserialization and serialization
Fixes#724
- We do not support full version negotiation, but this commit allows the
client to the send the correct version to match that of the server.
- There is one limitation: the GET /mcp request happens too early,
before we have deserialized the initialization response, so we do not
know the negotiated version yet. This request will have the client
latest version as Mcp-Protocol-Version value.
