Arkitect 2.0.1

Fixed

• The .gitignore advice names Draw.io Desktop's own autosave, .$*.bkp, a
  full copy of the diagram left beside any file it has open, as well as our
  *.backup-*. This repository ignores it too, and docs/privacy.md lists it
  (#252).
• The Draw.io skill's default reading was brought 300 bytes under its
  12,000-byte budget, where it was 13 before #256; #252 then took 17, leaving
  283. The comparison pattern says the same in
  fewer words, and SKILL.md drops a non-negotiable that step 4 already states
  and shortens one sentence. This makes room for #240, #248 and #252 (#253).
• An Excalidraw node and the caption or sublabel under it share a group, so
  dragging an icon in the app takes its name with it. A library item keeps its
  own group inside the node's. It adds groupIds and moves no coordinate, so
  it ships as a patch; the committed examples are rebuilt and draw the same
  (#190).
• Draw.io renders leave a 20px margin round the drawing. Desktop's border
  defaults to 0, so every PNG was cropped flush and the legend or the last
  caption touched its edge. --padding N changes it and 0 restores the old
  crop exactly; the PowerShell adapter takes -Padding. The three template
  PNGs are re-rendered; the contact sheets are Chrome screenshots and did not
  change (#249).
• A key at the top of a spec that neither builder reads is named under
  unknownFields, with a hint for edge, node and boundary, and in
  Excalidraw for pages and context. A misspelled edges used to drop every
  connector without a word. A key starting with _ is a comment, as in the
  committed templates (#221).
• The Draw.io skill no longer says there is no PDF export: render --format pdf
  has written one since the renderer was added, and references/rendering.md
  now shows it. A test fails if either skill denies a format its renderer
  accepts (#256).
