Description

Fixes per-run dependency tracking for DOM bindings. Reactive children (() => value), reactive class/style getters, and watch previously subscribed only to the signals read on their first evaluation: a signal first read on a later run (e.g. a conditional branch that becomes live after a state change) was never subscribed, so updates to it didn't re-render. Stale deps were also never pruned.

Root cause: these bindings registered their body as the subscriber via track(commit). On re-notification the body ran with no tracking context (currentSubscriber === null), so recordDependency was a no-op and the dependency set was frozen after the first run — unlike derived/effect, which re-run through retrack.

Fix (centralized): track()'s no-explicit-subscriber path now uses a self-re-tracking subscriber (reactiveBinding), so every re-run re-tracks deps — newly-read signals subscribe, abandoned ones prune. Also resolves query() data not reaching a status-branching consumer (if (q.loading()) …; return List(q.data())).

Additionally adds a dev-mode warning (tree-shaken in production) when a lone string argument looks like a CSS class list (div("space-y-6")), since a lone string is a text child — surfacing the footgun without changing behavior. Mirrored in sibujs-ui via normalizeArgs.
