Pull Request Overview

This PR bumps the mcp-go dependency to v0.31.0 and migrates all MCP tool parameter parsing from the old common.RequiredParam/common.OptionalParam helpers to the new request.Require* and request.Get* APIs. It also adds a new OptionalParamObject utility and updates Kafka header parsing to use string-based entries.

• Bump mcp-go from v0.28.0 to v0.31.0 in go.mod and go.work.sum
• Replace common.RequiredParam/common.OptionalParam with request.RequireString, RequireStringSlice, GetString, etc.
• Add OptionalParamObject in pkg/common/utils.go and adjust autoFailoverPolicyParams handling
• Update Kafka produce tools to accept headers as ["key=value"] strings and parse them via ParseMessageConfigs

• This now treats autoFailoverPolicyParams as required and errors when it’s absent. Previously it was optional—consider allowing a missing key to default to an empty map for backward compatibility.

• [nitpick] The new OptionalParamObject helper lacks a godoc comment—adding a description of its behavior and return values would improve overall code clarity.
