Phase 10: CalDAV full lifecycle, update_note, dashboard inline streaming, keyboard shortcuts

Backend:
- caldav.py: Full event lifecycle — update_event, delete_event; VTODO suite —
  create_todo, list_todos, complete_todo, delete_todo; list_calendars; timezone
  support via ZoneInfo; reminders via VALARM; attendees; multi-calendar search
  (_get_all_calendars scans all calendars when no specific one is configured)
- tools.py: New update_note tool (find by title + replace/append modes),
  7 new CalDAV tool definitions, corresponding execute_tool cases
- llm.py: Update system prompt — add update_note guidance, full CalDAV action list
- intent.py: Confidence scoring (high/medium/low) + should_execute property;
  conversation history support for anaphora resolution; routing rules for
  update/delete events, todos, update_note vs create_note disambiguation,
  time-period → list_events (not search_events), reminder_minutes conversion
- generation_task.py: Parallel fetch of tools + intent_model setting; dedicated
  intent model (OLLAMA_INTENT_MODEL env var or per-user intent_model setting)
- config.py: Add OLLAMA_INTENT_MODEL env var

Frontend:
- HomeView.vue: Inline streaming response (no navigation); quick action chips;
  isConversational computed — prominent "Continue this conversation" CTA when
  no tool calls; auto-focus chat input on mount via chatInputRef
- DashboardChatInput.vue: defineExpose({ focus }) for external focus control
- ChatView.vue: Escape key handler — close picker → close sidebar → clear
  textarea → navigate home; onUnmounted cleanup
- App.vue: Global ? key shortcut toggles keyboard shortcuts overlay; shared
  state via useShortcuts composable; Transition animation
- AppHeader.vue: ? button for shortcuts overlay discoverability
- useShortcuts.ts (new): Shared showShortcuts ref + open/close/toggle helpers
- ToolCallCard.vue: note_updated, event_updated, event_deleted, calendars,
  todo, todos, todo_completed, todo_deleted label cases + render blocks
- SettingsView.vue: Intent model field + caldav_timezone setting
