Subject: docs: document code block wrapping and the copy button

Records why the block style carries white-space:pre-wrap and why the
padding is margins plus a spacer line: Qt's markdown stylesheet does not
cover pre, and Qt ignores padding and vertical margins on it. Also
describes the copy button and the constraints behind its shape, since
neither a widget nor :hover is available in Qt rich text.

 - A dismiss (✕) button on status-line messages. They previously stayed until
   some later action replaced them; any status message can now be cleared
   without waiting.
+- A copy button on every fenced code block, below it on the right. Qt rich
+  text has no widgets and no `:hover`, so it is an anchor in the same internal
+  scheme dispatch the thinking and search toggles use, and hovering is a
+  re-render driven by `QTextBrowser.highlighted()`. It is grey at rest, takes
+  the highlight colour under the pointer, and becomes a green tick for a
+  moment once used. The text comes from the source markdown, since Qt emits
+  one `<pre>` per line and the block cannot be recovered from the rendered
+  HTML.
 
 ### Fixed
 
+- A long line in a code block widened the whole transcript and left it
+  scrolling sideways. Qt's markdown stylesheet wraps `p` and `li` but not
+  `pre`, and it is dropped when only the body fragment is kept, so the block
+  style now carries `white-space:pre-wrap` itself.
+- Code blocks sat flush against their tint. Qt ignores `padding` and vertical
+  margins on `<pre>`, so the inset now comes from left and right margins and
+  the room above and below from a tinted spacer line.
 - Model listing crashed when a provider's `/v1/models` endpoint returned a
   bare JSON array instead of the standard `{"data": [...]}` envelope. The
   parser now accepts both shapes.
