feat: agent summoning system, todo improvements, security fixes, double-execution bug fix

- Add summon/retrieve tools for spawning child agents in new tabs
  - summon: non-blocking, returns agent_id immediately
  - retrieve: blocking, waits for child to finish, returns result
  - Child tools are intersected with parent permissions (no privilege escalation)
  - Working directory validated to stay within workspace
  - Abort controller stops orphaned agents on tab close
- Rename task_list tool to todo with comprehensive usage guidance in system prompt
- Rename PermissionLog.svelte to ToolPermissions.svelte
- Add 'Summon agents' toggle to tool permissions UI
- Redesign TaskListPanel with DaisyUI checkboxes (indeterminate for in-progress)
- Remove 'blocked' status from task system
- Add tab-created WebSocket event for child agent tab visibility
- Add HMR cleanup for WebSocket connections (close stale connections on hot reload)
- Fix ensureAssistantMessage to not throw on closed tabs
- Fix double tool execution: remove execute from AI SDK tool() in registry.ts
  (agent.ts already executes tools manually via executeToolWithStreaming)
- Fix all pre-existing test failures (missing mocks, stale API signatures)
- Add debug info to copy button (tab ID, injected skills, all tab IDs)
- Add tab ID and tools to conversation copy output
