Sækja massCode 5.5.0

massCode 5.5 expands Notes into a more complete task workspace, adds the browser Clipper, and makes it easier to migrate from other tools.
Tasks In Notes
- Added task notes: tasks now live inside Notes and use the same markdown editor, folders, tags, favorites, internal links, and navigation history.
- Added task properties: status, priority, and due date.
- Added task-focused views in the Notes Library: Tasks, Today, Upcoming, and Completed.
- Tasks can be created with Cmd+T / Ctrl+T, from the app menu, or from the create menu in the Notes list.
- Regular notes can be converted to tasks and back.
- The Notes list now shows task checkboxes, priority, due dates, overdue state, and completed state.

massCode Clipper
- Added massCode Clipper for saving browser content into the local app.
- Added Chrome, Firefox, and Safari builds.
- The Clipper can save:
- selected text as a Code snippet;
- selected text or readable page content as a Note;
- the current page or selected link as an HTTP GET request.
- Added local Integration API authentication through the API port and token in Preferences.

Imports
- Added a shared import workflow with a preview before anything is written to the vault.
- Code imports now support VS Code snippets, Raycast snippets, SnippetsLab, and public GitHub Gists.
- Notes imports now support Obsidian markdown folders while preserving folder structure where possible.
- The import dialog shows the detected source, item counts, folders, tags, and warnings for unsupported source data.
- Import actions are now available from sidebars and the Command Palette.

Interface Improvements
- Added keyboard delete shortcuts for selected items in Code, Notes, HTTP, and Math Notebook.
- Delete and Cmd+Backspace now work in lists and folder trees while avoiding inputs, editors, menus, and dialogs.
- Fixed Notes sidebar folder tree overflow.
