feat: implement toast priority queue

[segunadebayo]

📝 Description

Add priority-based queue system for toasts inspired by Adobe Spectrum's design guidelines. Toasts now support priority
levels (1-8, where 1 is highest priority) with automatic priority assignment:

• Error toasts: Priority 1 (actionable) or 2 (non-actionable) - always shown first
• Warning toasts: Priority 2 (actionable) or 6 (non-actionable)
• Loading toasts: Priority 3 (actionable) or 4 (non-actionable)
• Success toasts: Priority 4 (actionable) or 7 (non-actionable)
• Info toasts: Priority 5 (actionable) or 8 (non-actionable)

When the maximum number of toasts is reached, new high-priority toasts are queued and displayed as soon as space becomes
available, ensuring critical notifications are never missed. Custom priorities can be set using the priority option.

Additionally, when using toast.promise to track a promise, the success options can now specify type as either
success or warning for more flexible promise result handling.

⛳️ Current behavior (updates)

Toast appears in order

🚀 New behavior

Everything looks great, excellent work. Quick question: will an Error toast override any toast that is currently displayed?

CMIIW, but according to the spec, if another toast type is visible, an Error toast should be shown immediately and replace the last visible toast when the max number of visible toasts has been reached.

That might be a breaking addition. We can consider adding this later.

For now, I might consider exposing methods to enqueue and dequeue a toast (for userland control)
