PR Summary

Low Risk
UI-only DS additions and animation styling tweaks with no auth, data, or API changes; minor visual difference for existing Menu/Select surfaces.

Overview
Adds a RightClickMenu design-system component that opens the same grouped MenuItem / SelectableList UI on right-click (or long-press) over wrapped children, with configurable position, portal rendering, keyboard loop selection, and a Ladle story.

collectSelectedIds is exported from menu so the context menu can mirror Menu selection highlighting. RightClickMenu is re-exported from the package entry.

SelectableList styling now picks a component recipe variant: Select keeps scale-based popoverIn / popoverOut; Menu (including right-click) uses opacity-only fadeIn / fadeOut. popoverIn / popoverOut keyframes in the preset use a slightly subtler scale (0.98 vs 0.96).

Two things jump out at me

1. you can't do it in a single press-release cycle, i.e. mouse-down, drag to the position of the item you want, release to select (as normal context menus can do)
2. I'm not a fan of zoom transitions on drop-down menus, I would use position only, or no transition at all

@lunelson - thanks for the feedback. Agree with you about the menu animation, I've updated it so that Menu only has a subtle fade in/out animation instead.

Re the right click issue, agree with you again, but this behaviour is actually driven by ark-ui - to fix it I'd need to override/re-implement the behaviour, which took claude ~150 loc. Claude also mentioned that right click behaves the way we expect it on windows + linux, and that this is an OSX only issue. I haven't/can't test to see if thats correct, but assuming it is, I think all things considered its not worth fixing this for now.
