fix(web): pull request replies can be added to chat - #34548
In the pull request panel, "Add to chat" only showed on the first comment of a thread, never on its replies. The idea was that the first comment's button sends the whole conversation. Two cases broke that:
A GitLab overview thread (a discussion on the whole merge request, not on a line) sent only its first comment, so its replies could not reach the chat at all.
A thread on a code line shared one 1,000-character limit across all its comments. When a bot's first comment is long, as CodeRabbit's usually are, the replies were cut off. A CodeRabbit reply that starts with a collapsed "Analysis chain" section also used up its share before the part people actually read.
I hit this on #33557, where I wanted to hand CodeRabbit's follow-up concern to the agent and couldn't.
Change
Every reply card in the Summary and Timeline tabs has "Add to chat". It sends the reply's whole conversation, the same chip as the first comment's button, so clicking both still adds one chip.
An overview thread goes into chat as one chip with every comment in it, labelled @author thread.
Each comment in a chat thread gets its own 1,000-character limit, and collapsed <details> sections go after the visible text. "Fix" keeps its current text.
Scope and approval
There is no issue for this. I think it fits the small-fix exception because the button exists on every other comment, and the change only makes replies reachable and their text intact. It touches the web client only. Mobile has no "Add to chat" for pull requests, and the diff tab's line comments already sent their whole thread.
Verification
New cases in pullRequestDetail.logic.test.ts cover an overview thread carrying its replies, a reply surviving a long first comment, and visible text placed before collapsed details. vp run check:changed passes.
On !5, the reply's button adds one #5 @TonybynMp4 thread chip with both comments in it.
On feat(git): choose which remote a branch pushes to #33557, the CodeRabbit reply's button adds the line thread with all four comments, and the reply's visible text ("I confirmed that a7eecd7dc6... One concern remains...") is in the chip.
Clicking the first comment's button afterwards adds no second chip.
Reply cards in the Summary and Timeline tabs had no Add to chat button, so a
reply in a GitLab overview thread never reached the composer. Every reply now
has the button and sends its whole conversation. Each comment gets its own
length bound, with collapsed details after the visible text, so a long bot
report no longer cuts the replies out.

Macroscope's review found this PR approvable — PR replies can now be added to chat with their full conversation, with text bounded per comment. The change is limited to user-selected composer context; the outstanding truncation finding remains subject to the separate correctness gate.

Comment cards can pass a whole conversation, including replies and overview threads, to chat. The context builder formats readable comments, prioritizes visible text over collapsed details, and limits context length while retaining newer replies.

Summary
Build context from thread comments apps/web/src/components/pullRequest/pullRequestDetail.logic.ts, apps/web/src/components/pullRequest/pullRequestDetail.logic.test.ts
The context builder formats readable thread comments with author attribution, moves collapsed details after visible text, and applies a character limit. It retains newer replies when trimming oversized threads and reports omitted replies. Tests cover replies, long opening remarks, collapsed details, and the length limit.
Pass thread conversations from comment cards apps/web/src/components/pullRequest/PullRequestSummaryTab.tsx, apps/web/src/components/pullRequest/PullRequestTimelineTab.tsx, apps/web/src/components/pullRequest/PullRequestDetailPanel.tsx
Summary and timeline cards can pass replies’ threads to chat. Overview threads can be selected as conversation subjects. The detail panel locates a selected comment through pullRequestConversationThreads.
Add to chat can drop a visible finding that follows nested collapsed sections closing on the same line, when the preceding collapsed content is long. The impact is limited to rare comment formatting, and the fix is small.

- Around line 710-713: Update the details-folding logic to track fenced code
blocks before recognizing `<details>` sections, and only move details content
when outside a code fence. Preserve fenced examples and their contents in their
original order, including when the comment is shorter than the limit.
- Line 713: Update the depth-tracking check for `</details>` so it recognizes
the closing tag even when text follows on the same line. Parse the closing tag
independently of trailing text, while preserving the existing depth decrement
behavior.
- Line 1267: Update the thread serialization in reviewCommentContextRecord to
enforce the 16,000-character wire limit while retaining the selected reply; when
content must be omitted, make that omission clear rather than silently
truncating the end of the thread.
- Line 1257: Update the Add to chat flow around the `comments` selection so a
partially loaded thread does not appear to provide complete thread context:
fetch the remaining replies before adding it, or clearly tell the user that the
chat context is incomplete. Preserve the existing behavior for fully loaded
threads and single comments.

Process every closing details tag on a line.
If nested sections end with </details></details>, this expression finds only the first closing tag. Line 740 then removes only one section from sections. The visible finding on the next line still enters folded. If the preceding analysis exceeds 1,000 characters, truncation removes that finding.
Process all section boundaries on the line. Extend the existing closing-tag test with nested sections that close on the same line and assert that the following finding survives.
