* feat(ui): redesign toast with accent rail and action slot
Align toast with the overlay-surface language from the user menu and
notification panel: left accent rail, tracked-mono kicker above the
message, lucide icons at 1.5px stroke, status-tinted progress bar.
Extend the toast store with an optional options object so callers can
pass an inline action button and override the default duration. Guard
removeToast against no-op dismissals so subscribers are not notified
when nothing changed, and cap the buffered queue at 20 to prevent
unbounded growth under spam.
* fix(ui): avoid impure Date.now in toast ref initializer
useRef(Date.now()) re-evaluates the impure call on every render and
trips the react-hooks/purity lint rule, even though only the first
render's value is retained. Initialize to 0 since the auto-dismiss
effect writes startRef.current = Date.now() before any read path
consumes it.
Show a loading notification with spinner and indeterminate progress bar
while Resource Hub operations are in progress, replacing the dead moment
between confirmation and result.
* refactor(ui): replace Sonner with custom Sera UI-inspired toast system
Replace the Sonner toast library with a custom implementation inspired by
Sera UI's glassmorphism design. The new system uses an external store pattern
with useSyncExternalStore for React integration, keeping the same
toast.success()/error()/warning() API so all 172 call sites required only
an import path change.
Key changes:
- New toast-store.ts: singleton store with identical API to Sonner
- New toast.tsx: Sera UI-faithful Notification component with Framer Motion
animations, frosted glass (backdrop-blur-xl), type gradient overlays,
animated progress bar (green→blue→sky gradient), and hover:scale-105
- Removed sonner and next-themes dependencies
- Rewired all 19 consumer files to import from the new store
* fix(ui): resolve ESLint errors in toast system
- Use const for listeners Set (prefer-const)
- Initialize startRef with 0 instead of Date.now() to satisfy
react-hooks/purity rule, set actual value inside useEffect
