- Fixed multiple batch management bugs (unlinking, settling, merging, async @const blockers, component‑level effects) and improved async resolve handling and outro branch resumption.
- Corrected hydration marker removal, directive ordering, and added tag name to a11y click‑event warnings; added safer promise rejection handling during batch commit.
- Optimized delegated event propagation by walking composedPath() directly.
