XML Grid View v0.1.1

• First marketplace release for VS Code, Open VSX and JetBrains.
• MIT license, icons, and marketplace metadata.
• New Flat view: the whole document as an outline sheet with Name and
  Value columns.
  • One row per element; attributes appear as @name rows under their element.
  • Rows collapse and expand, with Expand all / Collapse all.
  • Copy as indented TSV.
  • Enter/F4 goes to the source.
  • Find, including XPath.
  • In VS Code it's a Grid | Flat switch; in IntelliJ it's a third bottom
    tab (Text | Grid | Flat).
• Flat view selects cells like a spreadsheet.
  • Drag or Shift-click any range of rows across the Name and/or Value
    columns, or click row numbers for whole rows.
  • Ctrl/Cmd+C copies exactly the selected cells.
• New value inspector for long or structured values.
  • Open it with Shift+Enter on a Grid cell, Flat value or tree node, or
    with the ⤢ button on long values.
  • Plain text shows in full, with wrapping, search and copy.
  • JSON is detected automatically, with Tree / Grid / Text tabs:
    • Tree: collapse/expand and search.
    • Grid: drill down through nested objects and arrays, with a breadcrumb,
      sort, filters and copy.
    • Text: pretty-printed.
  • Numbers keep their exact literal, so 20-digit IDs don't get rounded.
  • Broken JSON shows the parse error and its location.
• IntelliJ: visible grid lines in the Grid and Flat tables, and row numbers in
  Flat.
• IntelliJ: verified against 2024.3 through 2026.2, with no deprecated API
  usages.
• IntelliJ: the viewer is now a Grid tab at the bottom of the editor
  (Text | Grid), replacing the Editor / Split / Viewer toggle.
