Upstream

Tracks upstream commit 40aa553, which builds on @base-ui/react v1.9.0
Ports everything upstream changed since v0.2.0. The full list of differences from the React API is in the public API differences.

Fix Number Field parsing of formatted negatives, unit labels and non-Latin digits
Fix Toast focus traps and timer resets during keyboard and pointer interaction
Fix Tab from a hover-opened Popover trigger stopping on a focus guard
Fix popups returning focus to hidden targets inside closed keepMounted popups
Fix popups losing the trigger that reopens them during their exit animation
Fix Menu clearing its filter query before the popup finishes closing
Fix OTP Field focus when the value shrinks externally. Focus moves to the first empty slot.
Fix Select dropping the selected item’s highlight when it’s disabled while open

Popups, floating elements, list navigation, Combobox and Select derive their synced state instead of copying it from effects. Opening and closing popups no longer floods the console with Solid’s EFFECT_RELAY_TEAR diagnostics in development.
Docs: focus-visible outline on the Toast demos, and heading badges stay in sync across the page index and search
