⚠️ Potential issue | 🟠 Major

Don’t replace the formatted cell value with a truncated preview.

Line 821 makes the grid display only the first 150 characters, so long JSON/text still cannot be fully viewed in the grid after resizing the column. Since UIExtensions now uses fixed initial widths, keep e.Value intact and let the grid clip visually.

🐛 Proposed fix 
-            if (e.Value is string str && str.Length > 150)
-            {
-                e.Value = str.Substring(0, 150) + "...";
-            }
+            // Keep the full formatted value available in the grid; the fixed
+            // column width clips the visual rendering without losing content.

if (e.Value is string str && str.Length > 150)
{
e.Value = str.Substring(0, 150) + "...";
}
// Keep the full formatted value available in the grid; the fixed

In `@LiteDB.Studio/Forms/MainForm.cs` around lines 819 - 822, The CellFormatting
handler in MainForm.cs is replacing e.Value with a truncated string (the if
block that uses str.Substring(0, 150)), which prevents the grid from ever
showing the full cell content even after column resize; remove that truncation
and leave e.Value unchanged (do not assign the shortened string), so the grid
will clip visually per UIExtensions' fixed widths; if a hover preview is desired
later, populate the cell's ToolTipText or similar instead of modifying e.Value.
