Context switcher

Give it a label and the trigger becomes a card naming what is being switched. The caller passes items so the trigger can draw the current one, then writes each row as its own form holding a koala-context-switcher-option button. The component draws the row; the form decides where the switch posts.

Without a label it is a compact top-bar button: the avatar, the name from extra-large screens up, and a chevron. Organisation and partner items draw an entity avatar from AvatarImageSrc, falling back to initials. With no group label the heading is inferred from the items when they are all organisations or all partners.

variant="rail" is the workspace rail's switcher. collapse-state is the Alpine expression that hides the name when the rail is collapsed, and collapse-state-initial tells the server which geometry to paint first so the rail does not jump on load. From small screens up the panel flies out beside the rail. Toggle the rail to see the collapsed trigger.

Past six items the panel grows a search box, focused as it opens, that filters the rows by name. search-placeholder and empty-label word it for what is being listed.
