0.9.0 — Archive & Markdown · Kandown changelog

Added: Archive folder and view — tasks can now be archived via a button in the drawer, which moves the file to .kandown/tasks/archive/, sets archived: true in the frontmatter, and hides it from the active board. A new header button toggles a dedicated Archive view listing all archived tasks with a one-click Restore action.
Added: archive and restore actions on the store, plus matching CLI server endpoints (POST /api/tasks/:id/archive and …/unarchive) and dev-mode vite middleware routes so the feature works in browser and server modes.
Changed: Unified markdown editor across the drawer — the task Report field and all subtask descriptions/reports now use the same BlockNote editor as the task description body, with the same slash menu, block types, and markdown round-trip guarantees. Wysimark and its marked-based preview have been removed entirely.
Removed: src/components/ui/MarkdownEditor.tsx (Wysimark), all wysimark CSS rules, and the @wysimark/react + marked dependencies.
Fixed: Legacy subtask report: / description: indented lines are now recognized by extractSubtasks and migrated to the canonical [REPORT] / [DESC] markers on the first open+save. Previously these lines were silently dropped on save, causing silent loss of subtask reports in older task files.
Fixed: YAML block scalar serializer no longer pads truly empty lines with two spaces, so the frontmatter report: | block stays byte-stable across open/save round-trips (no cosmetic git diff noise).
