Slice 6 of the worker state and queue consolidation refactor.
* Drop Manual, Planning, Planned, Draft, Waiting from the TaskStatus enum
and from the EF value converter; only the lifecycle values remain
(Idle, Queued, Running, Done, Failed, Cancelled).
* Add migration RetireLegacyTaskStatus that rewrites existing rows:
manual/draft -> idle, planning -> idle+planning_phase=active,
planned -> idle+planning_phase=finalized, waiting -> queued+blocked_by
derived from sort_order via a CTE with LAG().
* Reroute every call site that compared/set legacy values to the new
three-field model (Status + PlanningPhase + BlockedByTaskId), including
the planning repo helpers, MCP services, the planning chain coordinator,
and the UI view-models. TaskRowViewModel now exposes PlanningPhase to
drive the planning badge.
* Refresh Worker/CLAUDE.md and Data/CLAUDE.md, the docs/plan.md status
section, and the planning verification notes in docs/open.md.
Slice 1 of the worker-state-and-queue-consolidation refactor — additive only,
no caller changes. Introduces the new orthogonal status model:
- TaskStatus gains canonical Idle and Cancelled values; legacy values
(Manual, Planning, Planned, Draft, Waiting) stay around until slice 6.
- New PlanningPhase enum (None/Active/Finalized) for parent tasks.
- New BlockedByTaskId FK on TaskEntity for sequential chain ordering;
ON DELETE SET NULL so orphaned children become pickable.
- EF migration adds planning_phase and blocked_by_task_id columns plus
the idx_tasks_blocked_by index. Also picks up an unrelated drift in
app_settings.default_permission_mode that had been changed in code
(commit 14cc9fb) without a migration.
- New TaskStatus.Waiting for sequential subtask chains.
- New TaskEntity.CreatedBy column with migration AddTaskCreatedBy.
- TaskRepository.GetByCreatorAsync for filtering by creator.

Data layer: Paths helper with ~/%USERPROFILE% expansion, SqliteConnectionFactory
(WAL + foreign keys), SchemaInitializer that applies the embedded schema.sql, and
POCO entities for lists/tasks/tags/worktrees.
Worker: WorkerConfig loader (~/.todo-app/worker.config.json with defaults),
WorkerHub exposing Ping(), and Program.cs wiring Kestrel to 127.0.0.1:<port>,
SignalR at /hub, schema applied on startup.
Pins Microsoft.Data.Sqlite and Microsoft.Extensions.Hosting to 8.x for net8.0
compatibility.
