Task work log, inline writing assistant, task editor sidebar layout

Backend:
- Migration 0021: task_logs table (FK → notes + users, CASCADE, indexed)
- models/task_log.py: SQLAlchemy model with to_dict()
- services/task_logs.py: CRUD with ownership checks, _UNSET sentinel for optional duration clear
- routes/task_logs.py: GET/POST/PATCH/DELETE /api/tasks/<id>/logs
- services/tools.py: log_work LLM tool (resolves task by title, creates log entry)
- services/generation_task.py: retry assist generation up to 3× on HTTP 500

Frontend:
- types/task.ts: TaskLog interface
- TaskLogSection.vue: chronological work log with date+time timestamps, duration badge, inline edit, autofocus
- InlineAssistPanel.vue: streaming preview + diff review rendered inline in editor column
- useAssist.ts: removed chatStore.chatReady gate; toast notifications for errors
- NoteEditorView.vue + TaskEditorView.vue: inline assist panel, aside restricted to idle state
- TaskEditorView.vue: two-column layout (editor+log left, metadata sidebar right), body defaults to Preview, sidebarOpen accordion for mobile
- editor-shared.css: .assist-active-hint style
