feat: align datasource plugin with generic workflow

Problem

The TypeScript Kimi Datasource plugin exposed a stock-specific query_stock MCP tool, while the Python plugin exposes only the generic discovery and call tools. That split kept a hard-coded shortcut and a separate skill workflow in the TS plugin.

What changed

• Removed query_stock from the MCP tool list and handler.
• Updated datasource skill instructions to use get_data_source_desc before call_data_source_tool, matching the Python plugin workflow.
• Bumped the official datasource plugin and marketplace version to 3.1.0 and added a plugin changelog entry.
• Added a regression test for the two-tool MCP surface.

Publish the removed MCP tool as a major change

This release removes the public query_stock MCP tool, so any existing prompt, automation, or saved workflow that calls mcp__plugin-kimi-datasource-data__query_stock will now get Unknown tool, but the plugin is advertised as a 3.0.0 → 3.1.0 update. Since removing a command/tool is a breaking change, either keep a compatibility shim for query_stock or ship this as a major version so marketplace users are not offered a non-breaking upgrade that breaks existing calls.
