Mouse drags start and end inside rendered list items, so the clipboard serializer dropped item semantics even when the visible marker was selected. Treat the marker as explicit selection intent while keeping text-only selections unmarked.
Selections contained inside formatting copy only their visible content. Preserve Markdown syntax when the range includes or crosses the semantic element, while retaining list and table structure needed to serialize child boundaries.
* fix(app): keep line breaks and indentation in copied code
#2930 strips the pre/code tags from a partly selected code block, which
is right for the Markdown syntax but leaves the code itself going
through Turndown as prose. Turndown collapses whitespace, so two
selected lines arrive as one, the indentation is gone, and
Markdown-significant characters come back escaped.
Divert a partial code selection before that: copy the selected text
verbatim. Fully selected regions are untouched and still produce a
fence, which is what hasSelectedAllContents was already deciding.
The html half needs pre for anything multi-line -- HTML collapses
newlines too, so a rich paste target would lose the lines the same way.
A single line stays undecorated, matching the rule that a partial
selection does not carry its container's formatting.
Two trailing-newline fixes ride along, since both make a paste run code
nobody asked to run. Newlines between rendered lines are their own text
nodes, so a selection that overshoots the end of a line carries one;
strip it. The block's Copy button was handed the raw fence body, which
ends in a newline; hand it the rendered text instead.
* fix(app): strip every trailing blank line from copied code
The Copy button stripped one trailing newline, so a fence whose author
left a blank line before the closing delimiter still put an executable
newline on the clipboard. Pasting that into a terminal runs the last
line, which is the thing the strip existed to prevent.
Both copy paths now share one regex in markup.ts and remove every
trailing break, plus any indentation that followed the last one.

* fix(app): respect assistant copy selection boundaries
Selection serialization reintroduced semantic ancestors even when the user selected only their inner text, causing list markers and code delimiters to expand beyond the visible range. Preserve semantics only for complete selected nodes, and keep rich list payloads compatible with text composers that prefer HTML.
* fix(app): preserve loose list copy breaks
