[Feature Request] Add persistent status line displaying active model

Bug Description
There is no persistent indicator of which model is active. Checking requires running /model, which interrupts the flow when switching between windows running different models.

By comparison, Codex CLI displays the active model and reasoning level persistently at the bottom of its window. Screenshot attached showing both tools side by side.

Request: a persistent status line showing the active model, or a config option to enable one.

Environment Info

Errors

[]

When switching between terminal windows, clicking into an unfocused Claude Code window sometimes registers as a selection on whatever prompt option is currently highlighted, without pressing Enter. This has caused file edits to be rejected or accepted unintentionally mid-session.

Expected: the first click should focus the window only, not pass through to the interactive prompt.

This started within the past week. Running Claude Code 2.1.219 on macOS in Terminal.app. Other CLI tools in adjacent windows do not exhibit this.
