Previously model variants (reasoning effort) could only be cycled
with a keybind. Add a searchable selection panel accessible from the
command palette, matching the existing model selection flow. The
footer hint bar now advertises the command palette keybind instead
of the variant cycle shortcut.
When the prompt has text, Ctrl-c now clears it instead of
immediately starting the two-press exit sequence. An empty prompt
still triggers exit as before. The clear key is configurable via
the input_clear keybind.
Model labels now show provider display names (e.g. "GPT-5 · OpenAI")
instead of raw IDs, preferring configured providers over the full
provider list for resolution.
