Cli doesn't report its version on the initialize mcp call

[grantborthwick]

Describe the bug

When running an mcp server, the cli doesn't report its actual version to the server on the initialize message:

{"method":"initialize","params":{"protocolVersion":"2025-06-18","capabilities":{},"clientInfo":{"name":"github-copilot-developer","version":"1.0.0"}},"jsonrpc":"2.0","id":0}

I would expect version to match the cli version shown in the header instead of generically 1.0.0.

Affected version

GitHub Copilot CLI 0.0.401
