Add title attribute support to MCP @Tool annotation

[codeboyzhou]

Expected Behavior

Add title attribute support to MCP @Tool annotation.

Current Behavior

The MCP @Tool annotation has no title attribute now.

Context

For the underlying MCP Java SDK v0.11.0-SNAPSHOT, has added title field for the class McpSchema.Tool, so introduce this feature to spring-ai should be necessary.
