v1.6.6

Fixed changelog and KIS Investment Guide popups showing empty or cut-off content. Body now scrolls properly.

Now Playing info is hidden when viewing another member's profile via member toggle.

Calendar dropdown no longer hidden behind parent containers. Uses React Portal with fixed positioning.

New Timeline tab below kanban board with Discussion toggle. Shows tasks sorted by creation date with title, description preview, assignee/CC avatars, and click-to-navigate. Supports pagination.

Expanding a task folder in History shows a Timeline panel between Done and Cancelled columns. Cancelled column auto-hides when Timeline is active for better readability.

Dashboard, DM, MEMO, and Users section collapse states now persist across page navigation via localStorage.

Deleting a task navigates back to the Kanban board when in folder mode, instead of always returning to the dashboard.
