Add automatic uninstall of duplicate manual MCP servers

When the bundled MCP provider is used (VS Code >= 1.101.0 with MCP API support),
automatically detect and uninstall any duplicate manual MCP installations that
were previously set up via the CLI when the IDE didn't support bundled MCP.

This prevents duplicate MCP servers from coexisting when an IDE adds support
for VS Code's native MCP API.
