v0.2.1

Fix: separator hover/drag dead in packaged builds (issue #2)

The packaged app's Tailwind build only generates classes its own code uses, so plugin-only arbitrary classes (w-[9px], group-hover:opacity-100) were never compiled into the shipped CSS. The sash strip collapsed to 0px width and pointer-events-none on the band wrapper left nothing hit-testable.

• Separator width is now inline (style={{width: 9}}) — immune to class generation
• Hover feedback via React state (onPointerEnter/onPointerLeave) instead of the missing group-hover variant
• Removed pointer-events-none from the band wrapper

Dev workflow

• Added prettier (pnpm devDep, .prettierrc.json = defaults, lockfile committed) — pnpm run format
• Manifest 0.2.0 → 0.2.1
