Widens `avoidCollisions` from `boolean` to `boolean | 'flip'` on the 6 overlays
that expose it (combobox, context-menu, dropdown-menu, link-preview, select,
tooltip) — the FloatingContent engine already decoupled flip from shift, so
'flip' (flip-only, no slide) works everywhere and lets an arrowless, non-shift
overlay take the native CSS-anchor path. Additive: `boolean` is unchanged.
- Public prop types + provider opts widened (types.ts + *-provider). JSDoc on
the 3 descriptive ones (combobox/select/tooltip) documents the 3 modes; the
terse `@default true` menu types keep their inline style (the type shows 'flip').
- Demos: the 4 that had an avoidCollisions checkbox (dropdown-menu, context-menu,
link-preview, tooltip) now expose a 3-way full/flip/off control.
Verified in a real foreground browser (Claude-in-Chrome):
- dropdown-menu + avoidCollisions='flip' + no arrow → routes to NATIVE
(data-floating-native, position-anchor link to trigger, zero JS transform,
placed correctly).
- context-menu correctly STAYS on JS with 'flip' — it anchors to the cursor
(a Measurable), which the dispatcher's virtualAnchor gate forces to JS. The
discriminator works as designed.
- tooltip / link-preview 3-way controls render.
0 new check errors; 41 overlay + floating tests green.
