* knip: Don't ignore exports that are only used within a given file

* knip: More pruning after rebase

* knip: Vite plugin config fix

* knip: vitest plugin config

* knip: Playwright config, remove unnecessary ignores.

* knip: Simplify project file enumeration.

* knip: simplify the config file patterns ?(.optional_segment)

* knip: tailwind v4 fix

* knip: A little more, explain some of the deps.
Should be good for this PR.

* knip: remove unused disabling of classMembers.
It's opt-in, which we should probably do.

* knip: floating comments
We should probably delete _one_ of these parallell trees, right?

* knip: Add additional entrypoints

* knip: Restore UserData that's exposed via the types for now.

* knip: Add as an entry file even though knip says it's not necessary.

* knip: re-export functions used by nodes (h/t @christian-byrne)
