fix(mcp): capture tool title in MCP client

[threepointone]

Summary

• Surface the MCP tool title on tools returned by MCPClientManager.getAITools(), so UIs can render the friendly title instead of the namespaced tool name.
• Prefers the top-level tool.title (per the 2025-06-18 MCP spec) and falls back to the legacy tool.annotations?.title.
• Mirrors the Vercel AI SDK fix in vercel/ai#11910.

Fixes #1360.

Notes

• No type changes needed: the MCP SDK's Tool schema already declares both title and annotations.title, and ToolSet[string] in ai already accepts title?: string.

Test plan

• Connect an MCP server that advertises a tool title (either top-level or via annotations.title) and verify title is present on the corresponding entry from getAITools().
• Verify tools without a title still work (field is simply undefined).
