feat: add research task system with SQLite store, agent tool, and web UI

Add a deterministic research task lifecycle managed via SQLite, enabling
the agent (via heartbeat) to discover and execute pending research tasks,
and users to create/monitor tasks from both the Mini App and web management UI.

- pkg/research: SQLite store with WAL mode, Task/Document CRUD, status
  transition validation (pending→active→completed/failed, reopen support)
- pkg/tools/research: agent tool with list_tasks, get_task, set_status,
  add_finding actions; findings written as markdown to research/{slug}/
- pkg/miniapp/api_research: Mini App API endpoints for task management
- web/backend/api/research: management UI API accessing same research.db
- web/frontend: research list page, task detail with document accordion,
  sidebar nav item, i18n (en/zh)
