0.11.0 — Lean Drawer · Kandown changelog

Removed: The subtask editor in the task drawer (add/remove/check subtasks and the per-subtask description/report fields). The subtask data model is untouched — tasks still keep their - [ ] / - [x] checklist in the .md file, and the per-card progress bar on the board still shows done/total. Editing subtasks just happens in the task file directly now, not in the drawer.
Changed: The drawer body is now strictly stacked: title → DESCRIPTION (full width) → REPORT (full width, below description). The previous side-by-side 7/3 grid is gone, so each editor gets full room to breathe and feels closer to a writing surface than a form.
Removed: The header subtask count chip (done/total doneSubtasks) — no more subtasks in the drawer header.
Removed: The focusedSubtaskIdx state and the toggleSubtask / changeSubtask / removeSubtask / addSubtask / insertSubtaskAfter / handleDescriptionChange / handleReportChange handlers — all dead code now that the subtask editor is gone. The SubtaskItem import is gone too (the component file is left in the tree since the data model still uses Subtask).
