i18n(ka): the pdfInfo thumbnail page error (#2914)

#2784 made zh-hant a language that translates every status and error message while #2930 added the shared parameter-check errors to the others; main's shared_param_check_errors_are_translated failed on zh-hant.

Align: a Horizontal & Vertical Align Center button (#1073); Align to Key Object makes the topmost selected object the key (#1221), and the palette's key entry reads Cancel Key Object (#1224). Pen: the nearest end wins over snapping, Alt on the last anchor edits it, and Enter, Escape or a tool switch finish a handle preview as one undo step (#821). Direct Selection: a click on an anchor of an already selected path selects that anchor alone (#1237). Make Compound Path keeps the backmost object's paint, and a selected member reads and changes the compound's fill rule (#1225). Shape Builder and Live Paint no longer turn a line's loose end past a crossing into a piece that runs out and back (#1230). Art moved or duplicated with an artboard follows Transform Pattern Tiles (#1219). A click with the Rectangular Grid tool opens its options dialog (#1169). Commands that change nothing (Lock, Hide, Transform Each, Rearrange Artboards and others) add no undo step (#1233). Saving with missing placed files keeps their relink data, and .ai export honours the chosen artboards (#718). SVG export keeps Unicode data-attribute names, and SVG Options refuses an invalid artboard range (#989). CMYK colours given in percent with a component under 1 keep their scale (#1249). Colour Image Trace keeps close dark tones apart (#1247). macOS: the Save sheet has a Format menu (#1235). The Hand and Zoom tools show drawn cursors on every platform (#1238). Czech: the remaining strings are translated, and Pathfinder's Add reads "Sjednotit" (#1226). MCP: a lost reply reports that the edit may have happened instead of replaying it (#1246); `select.key` checks its id and agents can read the key object (#1222). Tests: the command sweeps and import fuzz tests fail on a panic caught by the engine's guard (#1218), and the envelope export test ignores PDF dates and file IDs (#1220). Effect › Artistic › Film Grain (Grain, Highlight Area, Intensity; Photoshop-style filters 29/57) (#1282), and Craquelure, Mosaic Tiles and Stained Glass redraw 25–30% faster with identical pixels (#1265). Direct Selection: clicking a segment selects only that segment, and Delete removes just it (#1300); Shift-click deselects one anchor of a path selected whole (#1263). Pen + Alt converts anchors of paths inside a selected group or compound path (#1306). The Curvature tool shows circular point markers without direction handles (#1284). Snap to Point: pressing near an anchor drags by that anchor, with Smart Guides on or off (#1313). Transform Again repeats the options of the transform it repeats (#1303). Aligning anchors that are already aligned adds no undo step (#1276), and type commands that change nothing record none either (#1316). Simplify keeps the path selected with its new anchors, and its dialog previews and shows the anchor count (#1305). Adding a stroke colour to an unpainted zero-width stroke gives it a visible 1 pt width (#1256). The Eyedropper samples locked objects, template layers and art outside isolation mode (#1260), and shows a pipette cursor (#1288). Fonts named by their full name resolve to the right face (#1267), and Proportional Metrics brings the matching kerning (`apkn`, `vkrn`, `vapk`) (#1291). Artboards: Escape leaves Artboard editing (#1296), Document Setup's Edit Artboards switches to the Artboard tool (#1294), and the Artboard tool starts on the active artboard (#1309). New and imported documents use the Gridline every and Subdivisions preferences (#1314). Send to Current Layer refuses a hidden or locked current layer (#1301), and layer row commands check explicit ids (#1255). Links: Find in Folder… finds missing linked files in a folder and its subfolders and can copy them into the document's folder (#1287). Image Trace traces images over 64 megapixels scaled down instead of refusing them (#1315). DXF export marks closed curves as closed SPLINE entities (#1320). EPS import: closepath respects the path size limit (#1311). The interface is available in Hungarian (#1302), and more Czech labels are translated (#1259). Linux RPMs declare shared-library capabilities (#1290). CI pins every third-party action to a verified commit (#1321).

Command parameters from agents and files checked before anything changes (paint, place, cuts, dashes, crop, asset ids, anchors, paths, distort; #984–#999); command dialogs keep whole numbers whole, so Create Object Mosaic takes the tiles typed (#1000); stepper arrows take Shift (×10) and Ctrl/Cmd (÷10) like the arrow keys (#991). Exports and Rasterize supersample Art Optimized edges, so shapes meeting edge to edge leave no seam (#983). Character and paragraph styles take leading, kerning, mojikumi and the other attributes left out at their defaults (#1001). Drawing, typing and pasting with no layer shown and unlocked is refused instead of adding art to a hidden or locked layer (#1002). MCP `add_text` gives type on or in a path the colour asked for (#1003). MCP `screenshot` of a connected app renders the artboard asked for (#1004). `vectorcraft-cli run` ends quietly when its reader closes early (#1005). Select › All on Active Artboard selects on the artboard made active, not always the first (#1006). Reverse Gradient keeps off-centre midpoints, mirrored (#1007). A polar grid with no radial dividers draws none (#1008). Use Precise Cursors also covers the Pen's join pointer (#1009). SVGs with one absolute and one unitless root side import at their size, unstretched (#1010). DXF US survey inches, yards and miles open at their size and name (#1011). A file placed into a document with no other links follows its first change even while the app sits idle (#1031). PDF import keeps the style a font name says when the file doesn't embed the font (#1023). Shift selects ruler guides and art together, and Delete removes both (#1022). Open filled paths are hit by their fill on every side, the rotate cursor bows around the corner it is at, the flip icons match their flips, the Color Picker previews on the selection, and Properties › Transform reaches Scale Corners and Scale Strokes & Effects (#1036). Offset Path and the other booleans finish on outlines where the sweep used to loop until memory ran out (linesweeper 0.5, #1028). Floating panel groups stack into sets that move together, collapse to their tabs and dock as extra dock columns that scroll (#1020). Ruler guides live on layers: listed in the Layers panel, shown, hidden, locked, duplicated, merged and deleted with their layer, and moved between layers (#1021). A `.ai` whose editing data uses global process colours (`Xk`/`XK`) or pattern fills keeps its sublayers: the colours come in as global swatches at their tint, the patterns as pattern swatches (#1025). A `.ai` in PostScript form opens through its layers, read from the program itself, also when it names the prolog defining its operators without including it, as Rhino and other CAD apps write it (#1027). A fill or stroke chosen while the Type tool has characters selected colours just those characters (#1063). Scaled type shows its scaled font size, leading, baseline shift and horizontal scale in the Character panel, and a size typed there is the size you get (#1034). Character panel menu › Proportional Metrics sets Japanese and Chinese full-width glyphs on the font's proportional widths in horizontal type (#966). Align, Distribute, Move, Arrange, Lock, Hide, Ungroup and other Object commands that would change nothing no longer record an undo step or mark the document changed (#1060). Spot colours defined in Lab open with their Lab values from `.ai` and PDF files, instead of as wrong RGB colours or their CMYK equivalents (#1032). Build scripts leave a generated source they wouldn't change untouched, so the next build doesn't compile most of the workspace again where file times lose their sub-second part (#1051). A fill colour recolours the gradient mesh point last clicked with the Mesh tool or Direct Selection, and a Mesh tool click on a mesh's point selects that mesh (#1052). The All Tools drawer stays two tools wide instead of filling a wide window (#1054). Text Wrap's Make, Release and Options refuse a list of object ids with a malformed or unknown id instead of skipping it (#1055). A freeform gradient line with a malformed point index is refused instead of being shortened to the indices that are valid (#1056). The Corners dialog (`ui.corners`) refuses a malformed object id or a listed anchor that isn't a corner instead of editing the selection or the other corners (#1057). New View refuses a centre that isn't exactly [x, y] and a rotation that isn't a number, instead of trimming the one and saving the other as 0° (#1058). The command sweeps try junk scale, spacing and artboard values too, which they had skipped since before those bugs were fixed (#1059). EPS and PostScript `arc` and `arcn` with huge angles no longer hang the import, and an arc whose angles are whole turns apart is empty, as the PostScript reference defines it (#1062).
