v0.8.0

Added

• Added live text search in the main panel across the full content of open and
  hidden notes, ignoring case and accents, with Ctrl+F access and a clear action.
• Added profiles and expandable note groups, a permanent General group per
  profile, and restoration of each profile's last active desktop context.
• Added create/rename, cross-profile note movement, and container deletion with
  note transfer or existing soft-deletion behavior.
• Added active-group, current-profile and all-profile search scopes with
  explicit opening of external results and profile/group breadcrumbs.
• Added atomic schema-5 migration of existing notes to Personal / General,
  validated private pre-upgrade snapshots and documented downgrade recovery.

Fixed

• Keep the bundled UX prototype readable for source-package validation by Lintian.
• Preserve individual hidden/open state and pending edits when switching groups.
• Keep the panel reusable after closing it; retain note action focus on refresh.
