@floating-ui/vue v2

Drop Vue 2 support as it reached EoL awhile ago

@floating-ui/react v1

Properly stabilize this package and refine APIs. I've kept it mostly backwards-compatible for 2 years now but it's showing some limitations.

It can be lighter/more tree-shakeable, and the APIs can be less confusing. Remove deprecations and tech debt.

@floating-ui/utils v1

This could be refined, stabilized and properly documented

@floating-ui/core,dom,react-dom,react-native

With CSS anchoring becoming more widespread in the future, it doesn't make sense to change anything/release a new major for these. The APIs have some minor issues, but these can be worked around externally easily (such as supporting logical sides without the confusing placement string)
