Learn: a Learn panel lists tutorials by skill, opened from Explore tutorials on the app bar

Window › Learn and a new Explore tutorials button beside the search icon on
the app bar show and hide the Learn panel. Its For you tab holds a Get started
section with a Quick skill guide card that opens the Skills tab. The Skills tab
lists VectorCraft's own skills with their tutorial counts and empty progress
rings; a skill lists its tutorials, a tutorial shows its numbered steps, and
Back goes up one level. The tutorials live in a data catalog whose test checks
unique ids, that every named tool and command exists and that no skill is
empty.

- window.learn {show?} shows, hides or toggles the panel; showing it also
  shows a hidden dock, and the panel counts as hidden while the dock is hidden
  or a full screen mode hides the panels.
- learn.list lists the skills and tutorials; learn.show {tutorial} opens one.
  A missing, non-string or unknown id is an error and changes nothing.
- New labels and messages have rows in every catalog. The tutorial text is
  English.

+
+Window › Learn and the Explore tutorials button beside the search icon at the right end of the app bar show and hide
+the Learn panel. Its For you tab holds a Get started section with a Quick skill guide card; choosing the card opens
+the Skills tab. The Skills tab lists VectorCraft's own skills, each with its number of tutorials and an empty progress
+ring. Choosing a skill lists its tutorials, choosing a tutorial shows its numbered steps, and Back goes up one level.
+The tutorial text is English. `window.learn {show?}` shows the panel (`show: true`), hides it (`show: false`) or
+toggles it (`show` omitted or null), and answers whether it shows; Window › Learn and Explore tutorials run it.
+The panel counts as hidden while the dock is hidden or a full screen mode hides the panels. Showing it shows a hidden
+dock; in a full screen mode it makes Learn the front panel, which shows when the mode ends, and answers false. Any
+other value of `show` is an error and changes nothing. `learn.list {}` → `{skills: [{id, title, tutorials: [{id, title, steps}]}]}`, in the order the Skills tab
+lists them, where `steps` is the number of steps. `learn.show {tutorial}` shows the panel on its Skills tab with that
+tutorial's steps → `{skill, tutorial, title, steps: [text]}`. A missing, non-string or unknown `tutorial` is an error
+and changes nothing. Behavior reference:

Ungroup and the release commands then bring back boxes square to the page (VectorCraft's own behavior; `bboxrotate::reset_bounding_box_squares_the_objects_inside_a_group`, `reset_bounding_box_squares_the_turned_members_of_a_square_group`, `reset_bounding_box_then_release_clipping_mask` and the other `reset_bounding_box_then_*` tests, `reset_bounding_box_leaves_the_art_of_an_unlinked_opacity_mask`).

   - The errors of the blend spine commands (Move Spine Point, Reshape Spine Segment, Add Spine Point and Delete Spine Point) show in the status bar in the interface language: each has a row in every catalog that translates all status and error messages and in Bulgarian (`blend_spine_param_errors_are_translated`).
   - The errors of the parameter checks that many commands share show in the status bar in the interface language: a value that is not a number where a number goes (`object.move` with `"dx": "60 mm"`, and `object.rotate`, `object.setBounds` and the other commands that call `check_numbers`), a missing number or index, `ids` that are not a list of object ids, an object id that is not a non-negative integer or names no object, and a date that is not Unix seconds. Each has a row in every catalog that translates all status and error messages, and in Bulgarian, Danish, Indonesian and Dutch (`shared_param_check_errors_are_translated`).
   - Export commands run through MCP, the control channel or the CLI refuse a key that no format takes, and a command that writes one format (`document.exportPdf`, `document.exportEps`, `document.exportDxf`) or takes one format's options (`document.pdfSettings`, `pdf.preset.save`) refuses a key that format doesn't take. An unknown key inside `marks`, `bleed`, `compression`, `output`, `advanced`, `security` or `flattener` is refused by its path.
