Object: Lock, Transform Each, Perspective and other commands that change nothing record no undo step

These commands edited the document even when nothing changed, so the
call recorded an undo step, emptied Redo and marked the document
modified:

- All Artwork Above and Other Layers (Object › Lock and
  Object › Hide) with nothing to lock or hide: no object above the
  selection, no other layer, or every one already locked (Lock) or
  hidden (Hide).
- Transform Each with no object to transform, and without Copy when
  both scales are 100% and there is no move, rotation or reflection.
- Rearrange All Artboards when no artboard moves, or with no artboard.
- stroke.widthPoint.set and stroke.widthPoint.copy when the profile
  comes out as it was, and stroke.widthProfile.set with the profile the
  strokes have already.
- Liquify when the stroke reshapes no path, and Puppet Warp given the
  pins the art holds already (rest: true), or without rest when every
  pin stays where it is and turns the art by 0° or is free.
- Define Perspective Grid with the grid the document has, Attach to
  Active Plane with no object, Release with Perspective on art that is
  not in perspective, Move Plane to where the plane is, without copies,
  and Move Plane to Match Object when the plane is there and active
  already.
- Move, Nudge and Transform in Perspective without Copy when no object
  moves (1e-9 pt or less along the plane or its normal, Snap to Grid
  included, or the identity), and Transform Again after one.

These commands now return without editing the document. The replies
have the same form as before. Transform Each with Copy and no object
to transform no longer empties the selection. Puppet Warp without rest,
with every pin where it is and turning the art by 0° or free, no longer
turns a live shape into a plain path. All Artwork Above still deselects
selected objects that are hidden or locked. Width Point counts a change
of 1e-9 or less in a point's place or width factor (its width over half
the stroke weight) as none. OK in Width Point Edit with the widths it
shows, with or without Adjust Adjoining Width Points, records no undo
step. After a move in perspective that moved nothing, Transform Again
repeats the identity.

 - **Fonts:** a font is found by any of its names (family and style in every language of its name table, legacy family/style pairs, PostScript name), so documents from other apps open with the font they name; Find Font and `text.fonts` say for each font whether it was found exactly, by another name, substituted or missing, and how many glyphs are missing. PDF and `.ai` import brings Japanese text back as live type: CID fonts without a ToUnicode map read through the standard CMaps, vertical columns (WMode 1) as vertical type, letter spacing as tracking; a glyph is live type only when the installed font (in the closest style of its family) draws the same glyph, and text in a font that isn't installed comes in as live type shown in the fallback font until the font is installed (exports that draw it — PDF, EPS, EMF/WMF, raster, SVG outlines or embedded fonts — warn that they wrote the fallback font; `textAs: outlines` keeps the PDF's embedded glyphs). Two installed versions of one family and style (a font library keeping an old file beside a new one) both load, the first staying the one the family and style resolve to; PDF and `.ai` import tries each version when the glyphs differ, and type set in a version other than that one names it (`CharStyle::font_version`), which layout, the substituted-glyph highlight, Find Font, Package and Document Info follow. Fonts outside the font folders are listed too: those font services such as Adobe Fonts load on Windows, through DirectWrite, and those apps and font managers register with CoreText on macOS (#579). When a document opens with fonts that aren't available, fonts used only in symbols included, a Missing Fonts dialog lists them after the linked-file questions, with Find Fonts (Type › Find Font on them) and Close. Its Find in Folder… (in Find Font too) searches a folder on several threads, reads only what the font scan reads of font files and skips app packages, the Program Files and ProgramData folders, the system's folders and the app data folders in a home folder; Add Fonts copies the font files the user chooses, suitcase fonts with their resource fork, into VectorCraft's own Fonts folder, which the desktop app and `vectorcraft-cli` read (`text.missingFonts`, `text.findFontFiles`, `text.addFontFiles`).
 - **Files (M4):**
   - `.vectorcraft` (lossless JSON, compressed, atomic saves, save down to v1), Save As with a format chooser, Save a Copy, Revert, templates, Data Recovery after a crash (browser tabs hold their copies with Web Locks too, so a background tab's copies are never taken for a crash's, and a tab repairs copies another removed when it resumes: #367), background save and export. The desktop app writes its warnings and errors (graphics adapter, a lost graphics device, panics the guard recovered from) to standard error and to `logs/vectorcraft.log` next to the preferences, the two previous runs kept and each file capped at 16 MiB, so a launch without a terminal still leaves something to attach to a bug report (#465).
