Add an xs size variant to the Switch primitive and use it for the provider
edit submenu toggles. In appearance settings, drop the redundant selection
Pills (the UI already shows the active choice), move the Color Mode and Tool
Call Display segmented controls into the section header's right side
(responsive: stacks under the heading on narrow widths), and shrink the
segmented control.
Add a base-layer rule giving every interactive control (button, select,
menu item, switch, tab, summary) cursor:pointer, and strip the now-redundant
hardcoded cursor-pointer from those elements (plain clickable divs/labels
keep theirs). Remove the divide-y separators from settings list sections so
they breathe.
- selectModel reports success; edits bail (and roll back) instead of landing
on the previously active model when a switch fails
- Fast toggle stays available to turn off a carried-over speed param even when
the new model has no native fast mechanism
- active row's "Fast" label derives from the same fastControl as the submenu
toggle, so it's consistent and handles standalone `-fast` model ids
Replace the status-bar model chip's modal with a Cursor-style dropdown:
- providers grouped by name in a stable order (no recency reshuffle on select)
- per-model hover-Edit submenu for reasoning effort + fast, gated by per-model
capabilities now surfaced in the model.options payload
- unified Fast toggle: flips the speed=fast param where supported, else swaps
to the model's `-fast` variant (base and variant collapse into one row)
- localStorage-backed "Edit Models" dialog to choose which models appear
Adds reusable dropdown primitives (DropdownMenuSearch, shared row/label
tokens, portaled + collision-aware submenus) and reads session state from
nanostores rather than prop-drilling, so editing options doesn't rebuild and
close the menu.
