   - Task handler generalized: `TaskHandler` (renamed from `EvolutionHandler`), repo-configured self-heal for any project, template lookup builtin → `~/.emrg/task-templates/<name>.md` → fallback
   - Daemon commands: `task_create/update/delete` + `task_template_create/list/update/delete` (tasks stored in `~/.emrg/tasks.yml`, custom type templates in `~/.emrg/task-templates/`)
