Fix 1: github_copilot/... models work again.

After v1.1.0 the LiteLLM usage was restructured, which broke models of the format github_copilot/... for me. The error was:

agent> Hello
Client error '401 Unauthorized' for url 'https://api.anthropic.com/v1/messages'
For more information check: https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/401
The API provider is not able to authenticate you. Check your API key.

https://api.anthropic.com/v1/messages

As you can see, it routed models like github_copilot/claude-sonnet-5 directly to Anthropic's API, instead of Github Copilot's.

Also, there was this warning when selecting such a model:

agent> /agent-model github_copilot/claude-sonnet-5

Warning for github_copilot/claude-sonnet-5: Unknown which environment variables are required.

Fix 2: local MCP servers with old-style password auth (instead of oauth) could not be used anymore; cecli gave some oauth error. This PR makes it so in this case cecli does not enter the oauth path anymore.

The copilot fix already exists in v1.2.2 with:
7924004

and the MCP fix is basically what was done for:
#633

Can you check out the v1.2.2rc2 pre-release version to confirm that these points are addressed?

I'll actually just push v1.2.2 as the official shortly and we can track if this PR still needs to exists

Can confirm this PR is obsolete (current upstream v1.2.3.dev3).
