Too many MCP servers results in continuous compaction

[adithyabsk]

Describe the bug

The CLI agent can end up in a degenerate state when you enable too many MCP servers that expand past the available context window of the model in question supporting the harness.

The CLI should detect this state and warn the user. In my case, I ended up with 94k / 128k context window consumed by tools

Affected version

GitHub Copilot CLI 1.0.37.
