[Bug] Terminal UI displays incorrect model name when subagents launch or switch models

Describe the bug
When a subagent is launched, the actual underlying model works properly, but the terminal interface displays the incorrect model name. This mislabeling occurs when explicitly suggesting a different model or when an automatic model switch takes place.

Steps to Reproduce

Launch a subagent task inside Claude Code.

Pass an explicit model override or trigger an automatic model change.

Observe the model name reported in the terminal output.

Expected Behavior
The terminal UI should accurately reflect the active model name being used by the running subagent.

Actual Behavior
The subagent executes with the correct model, but the terminal UI displays an incorrect model label/name.
