VSCode extension: no way to see the currently active model in the UI

In the terminal CLI, there's an optional statusLine feature (and /status) that can surface the active model persistently. The VSCode native extension has no equivalent — there's no status bar item, sidebar indicator, or setting to show which model (Sonnet/Opus/Haiku/etc.) is currently active.

Right now the only way to check is running /model or /usage on demand, which requires interrupting your flow to look it up.

Request: add a persistent model indicator to the VSCode extension UI — e.g. a status bar item, similar to the terminal's statusline — so the active model is visible at a glance without running a command.
