Add URL-type elicitation schema support allowing servers to request URL
input from users during tool execution. This enables out-of-band
interactions like payment processing or API key entry.
Breaking changes:
- `ElicitRequest` changed from a `record` to an `interface`.
- The original `ElicitRequest` record was renamed to `ElicitFormRequest`.
- `McpClient` builder `elicitation()` methods now accept `ElicitFormRequest` instead of `ElicitRequest`.
New APIs:
- `ElicitUrlRequest` record for URL-mode elicitation.
- `urlElicitation()` builder methods in `McpClient`.
- `elicitationCompleteConsumer()` and `elicitationCompleteConsumers()` builder methods in `McpClient`.
- `sendElicitationComplete()` methods in `McpAsyncServer` and `McpSyncServer`.
- `McpError.URL_ELICITATION_REQUIRED` and `McpSchema.ErrorCodes.URL_ELICITATION_REQUIRED`.
- `ElicitationCompleteNotification` record and `METHOD_NOTIFICATION_ELICITATION_COMPLETE` constant.

Resolves#356
Clarify the two-tier error model:
- Recoverable tool errors: use CallToolResult with isError(true)
- Protocol-level errors: throw McpError / let exceptions propagate as JSON-RPC errors

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
