* 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.
This pull request creates two modules, `mcp-json` and `mcp-json-jackson`. It removes the `com.fasterxml.jackson.core:jackson-databind` and `com.networknt:json-schema-validator` dependencies from the `mcp` module. The `mcp` module now only depends on `com.fasterxml.jackson.core:jackson-annotations`.
To use Jackson, you have to add `mcp-jackson` to your dependencies in addition to `mcp`. I added the dependency `mcp-jackson` to both `mcp-spring-mvc` and `mcp-spring-webflux` to avoid a breaking change in those modules.
It provides two [SPI](https://docs.oracle.com/javase/tutorial/sound/SPI-intro.html) `JsonSchemaValidatorSupplier` and `JacksonJsonSchemaValidatorSupplier` to allow easy replacement for consumers who don't want to use Jackson.
This pull request also ensures no `McpJsonMapper` is instantiated if one is provided via a builder method. Only if the builders don't receive a `McpJsonMapper` mapper, one is instantiated in the `build` method of the builder.
The logic behind this is to allow frameworks to provide a `McpJsonMapper` mapper singleton implementation and feed it to the builders without paying the price of instantiating `McpJsonMappers`, which will not be used. The goal is to be able to use the `ObjectMapper` singleton of an application also for the MCP code.

Introduces a new mcp-bom module to simplify dependency version management across
Spring AI MCP projects. The BOM allows users to import a single dependency that
manages versions of all MCP components, ensuring version compatibility and reducing
maintenance overhead.
- Adds mcp-bom module with managed versions for all Spring AI MCP dependencies
- Provides centralized version control through a single BOM import
- Removes explicit version declarations from documentation examples
- Adds dependency management documentation and updates existing docs to reference the new BOM
