+Add a `provider` slot to the TUI footer status line, so the status bar can show which provider serves the current model. List it in `[status_line].items` to enable it, and it is also available as `provider` in the `[status_line].command` JSON payload.

+The `provider` slot shows which provider serves the current model (`managed:` ids
+render without the prefix, e.g. `openrouter`), which disambiguates look-alike model
+names across providers. It is opt-in: list it in `items` to enable it.
