… brief tool split

support import md

Major changes:
- Split task CLI into modular files (task/, lifecycle, topic, doc, review, checkpoint, dep)
- Split builtin-tool-task into task + brief tools (conditional injection)
- Task review uses EvalBenchmarkRubric from @lobechat/eval-rubric
- Task workspace: documents auto-pin via Notebook, tree view with folders
- Task comments system (task_comments table)
- Task topics: dedicated TaskTopicModel with userId, handoff fields, review results
- Heartbeat timeout auto-detection in detail API
- Run idempotency (reject duplicate runs) + error rollback
- Topic cancel/delete by topicId only (no taskId needed)
- Integration tests for task router (13 tests)
- interruptOperation fix (string param, not object)
- Global TRPC error handler in CLI

🗃️ chore: consolidate task system migrations into single 0095

Merged 7 separate migrations (0095-0101) into one:
- tasks, briefs, task_comments, task_dependencies, task_documents, task_topics tables
- All fields including sort_order, resolved_action/comment, review fields
- Idempotent CREATE TABLE IF NOT EXISTS, DROP/ADD CONSTRAINT, CREATE INDEX IF NOT EXISTS

✨ feat: add onComplete hook to task.run for completion callbacks

When agent execution completes, the hook:
- Updates task heartbeat
- Creates a result Brief (on success) with assistant content summary
- Creates an error Brief (on failure) with error message
- Supports both local (handler) and production (webhook) modes

Uses the new Agent Runtime Hooks system instead of raw stepCallbacks.

✨ feat: add Review system — LLM-as-Judge automated review

Task review uses an independent LLM call to evaluate topic output
quality against configurable criteria with pass/fail thresholds.

- TaskReviewService: structured LLM review via generateObject,
  auto-resolves model/provider from user's system agent defaults
- Model: getReviewConfig, updateReviewConfig on TaskModel
- Router: getReview, updateReview, runReview procedures
- CLI: `task review set/view/run` commands
- Auto-creates Brief with review results

✨ feat: add TaskScheduler, multi-topic execution, and handoff context

- TaskScheduler: interface + Local implementation (setTimeout-based),
  following QueueService dual-mode pattern
- Multi-topic execution: `task run --topics N --delay S` runs N topics
  in sequence with optional delay between them
- Handoff context: buildTaskPrompt() queries previous topics by
  metadata.taskId and injects handoff summaries into the next topic's
  prompt (sliding window: latest full, older summaries only)
- Heartbeat auto-update between topics

✨ feat: add Heartbeat watchdog + heartbeat CLI

Watchdog scans running tasks with expired heartbeats, marks them as
failed, and creates urgent error Briefs. Heartbeat CLI allows manual
heartbeat reporting for testing.

- Model: refactored to use Drizzle operators (isNull, isNotNull, ne)
  instead of raw SQL where possible; fixed findStuckTasks to skip
  tasks without heartbeat data
- Router: heartbeat (manual report), watchdog (scan + fail + brief)
- Router: updateSchema now includes heartbeatInterval, heartbeatTimeout
- CLI: `task heartbeat <id>`, `task watchdog`, `task edit` with
  --heartbeat-timeout, --heartbeat-interval, --description

♻️ refactor: move CheckpointConfig to @lobechat/types

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

✨ feat: add task run — trigger agent execution for tasks

Task.run creates a topic, triggers AiAgentService.execAgent with task
context, and streams results via SSE. Supports both agentId and slug.

- Service: added taskId to ExecAgentParams, included in topic metadata
- Router: task.run procedure — resolves agent, builds prompt, calls execAgent,
  updates topic count and heartbeat
- CLI: `task run <id>` command with SSE streaming, --prompt, --verbose

✨ feat: add Checkpoint system for task review gates

Checkpoint allows configuring pause points in task execution flow.
Supports beforeIds (pause before subtask starts) and afterIds (pause
after subtask completes) on parent tasks.

- Model: CheckpointConfig type, getCheckpointConfig, updateCheckpointConfig,
  shouldPauseBeforeStart, shouldPauseAfterComplete
- Router: getCheckpoint, updateCheckpoint procedures; integrated with
  updateStatus for automatic checkpoint triggering
- CLI: `task checkpoint view/set` commands with --before, --after,
  --topic-before, --topic-after, --on-agent-request options
- Tests: 3 new checkpoint tests (37 total)

✨ feat: add dependency unlocking on task completion

When a task completes, automatically check and unlock blocked tasks
whose dependencies are all satisfied (backlog → running). Also notify
when all subtasks of a parent are completed.

- Model: getUnlockedTasks, areAllSubtasksCompleted (Drizzle, no raw SQL)
- Router: updateStatus hook triggers unlocking on completion
- CLI: shows unlocked tasks and parent completion notification
- Tests: 3 new tests (34 total)

✨ feat: add Brief system — schema, model, router, CLI

Brief is a universal Agent-to-User reporting mechanism, not limited to
Tasks. CronJobs, Agents, and future systems can all produce Briefs.

- Schema: briefs table with polymorphic source (taskId, cronJobId, agentId)
- Model: BriefModel with CRUD, listUnresolved (Daily Brief), markRead, resolve
- Router: TRPC brief router with taskId identifier resolution
- CLI: `lh brief` command (list/view/read/resolve)
- Tests: 11 model tests
- Migration: 0096_add_briefs_table.sql

✨ feat: add Task system — schema, model, router, CLI

Implement the foundational Task system for managing long-running,
multi-topic agent tasks with subtask trees and dependency chains.

- Schema: tasks, task_dependencies, task_documents tables
- Model: TaskModel with CRUD, tree queries, heartbeat, dependencies, document pinning
- Router: TRPC task router with identifier/id resolution
- CLI: `lh task` command (list/view/create/edit/delete/start/pause/resume/complete/cancel/tree/dep)
- Tests: 31 model tests
- Migration: 0095_add_task_tables.sql
