This PR supersedes #762

Context

We are bringing proper OSGi support to the SDK. See #562 , #574.

As part of this effort, we are bringing mcp-json back into mcp-core, see: #612 and #682

This means integrations tests inside mcp-core, which used to run with mcp-json-jackson3, cannot run as-is, as mcp-jackson-3 now depends on mcp-core and maven can't handle the cyclic dependencies.

Contents

  1. Add OSGi relevant metadata + bnd plugin
  2. Move mcp-json back into mcp-core
  3. Move integration tests to mcp-test
  4. Add jackson2 profile for running integration tests with jackson2.
