- Move toast viewport from top-right to bottom-left with slide-up animation
- Apply consistent transparent blur-glass styling across all tone colors
- Include agent names (from query cache) in agent status, run status,
and activity toasts instead of truncated IDs
- Show specific change details for issue.updated toasts (status, priority)
- Use "New comment by AgentName" instead of generic "Issue comment added"
- Add truncation helper for long body text
