v1.2.1: edit toolview uses DSH's native ToolRow/DiffBlock chrome (DisclosureRow, collapsed by default, file link, hover diff stat, Output card on error, code-card header with icon actions, 9-row fold); keeps line-number gutter; client render smoke test

 ## Diff cards in the Web UI
 
-The plugin ships a web client (`client.js`) that registers an `edit` tool view. Hashline, sloppy and apply_patch calls render as a diff card instead of raw patch text:
-- green added rows, red removed rows and gray context, using only DSH's theme tokens (`--dsw-alias-code-diff-added/-deleted`, `--dsw-alias-state-success/error-primary`, the code-block font), so it follows the active theme like the stock diff view;
-- a **line-number gutter** with the old and new file line of every row;
-- `+N -M` counts in the header, plus Wrap and Copy buttons.
+The plugin ships a web client (`client.js`) that registers an `edit` tool view. Hashline, sloppy and apply_patch calls would otherwise show raw patch JSON; instead they render with the **same chrome as DSH's own tool rows**, built from DSH's primitives (`DisclosureRow`, `TextShimmer`, `Tooltip`, its icons) with CSS copied from the stock `ToolRow`, `CodeCard` and `DiffBlock` modules:
+- the standard 24px row: edit icon, `Edit` title, a dot separator, the file path as a dotted link that opens the file, and a small monospace `+N -M` that turns green/red on hover or when expanded. Rows start collapsed and follow the turn's expand/collapse state, like every other tool;
+- a failed edit shows its first error line in red, and expanding it shows the standard **Output** card;
+- the expanded diff is the stock code card: a language header with the wrap and copy icon buttons, 22px-padded rows with the inset +/- bar, and the head/tail fold after 9 rows;
+- one addition: a **line-number gutter** with the old and new file line of every row.

+Colors come only from DSH theme tokens, so the view follows the active theme.
 
 The host attaches `oldStart`, `newStart` and `rows` to every hunk in `meta.diffs`, next to the standard `path`/`oldText`/`newText` fields. Older results without them still render, just without numbers.
