Added granular task state management to scheduled events/tasks with three states plus unclaimed. Tasks now support a full workflow from claiming to completion with visual feedback at each stage.
**New Task States:**
- **Unclaimed** (no RSVP event) - Task available for anyone to claim
- **Claimed** - User has reserved the task but hasn't started
- **In Progress** - User is actively working on the task
- **Completed** - Task is done
- **Blocked** - Task is stuck (supported but not yet used in UI)
- **Cancelled** - Task won't be completed (supported but not yet used in UI)
**Service Layer (ScheduledEventService.ts):**
- Updated `EventCompletion` interface: replaced `completed: boolean` with `taskStatus: TaskStatus`
- Added `TaskStatus` type: `'claimed' | 'in-progress' | 'completed' | 'blocked' | 'cancelled'`
- New methods: `claimTask()`, `startTask()`, `getTaskStatus()`
- Refactored `completeEvent()` and renamed `uncompleteEvent()` to `unclaimTask()`
- Internal `updateTaskStatus()` method handles all state changes
- Uses `task-status` tag instead of `completed` tag in Nostr events
- `unclaimTask()` publishes deletion event (kind 5) to remove RSVP
- Backward compatibility: reads old `completed` tag and converts to new taskStatus
**Composable (useScheduledEvents.ts):**
- Exported new methods: `claimTask`, `startTask`, `unclaimTask`, `getTaskStatus`
- Updated `completeEvent` signature to accept occurrence parameter
- Marked `toggleComplete` as deprecated (still works for compatibility)
**UI (ScheduledEventCard.vue):**
- Context-aware action buttons based on current task status:
- Unclaimed: "Claim Task" button
- Claimed: "Start Task" + "Unclaim" buttons
- In Progress: "Mark Complete" + "Unclaim" buttons
- Completed: "Unclaim" button only
- Status badges with icons and color coding:
- 👋 Claimed (blue)
- 🔄 In Progress (orange)
- ✓ Completed (green)
- Shows who claimed/is working on/completed each task
- Unified confirmation dialog for all actions
- Quick action buttons in collapsed view
- Full button set in expanded view
**Feed Integration (NostrFeed.vue):**
- Added handlers: `onClaimTask`, `onStartTask`, `onCompleteTask`, `onUnclaimTask`
- Passes `getTaskStatus` prop to ScheduledEventCard
- Wired up all new event emitters
**Nostr Protocol:**
- Uses NIP-52 Calendar Event RSVP (kind 31925)
- Custom `task-status` tag for granular state tracking
- Deletion events (kind 5) for unclaiming tasks
- Fully decentralized - all state stored on Nostr relays
