feat(web): quote reply to pull request comments

[dominic-r]

Replying to a specific comment on a pull request means copying it into the composer and hand-prefixing every line with > . Each comment in the Summary tab's conversation now carries a quote-reply button that does what GitHub's does: the composer prefills with the comment quoted line by line and focuses with the cursor on the empty line below the quote, ready for the reply. Quoting appends under anything already drafted instead of replacing it, the button only shows when the viewer can comment and the comment has words to quote, and it stays disabled while a comment is posting so the on-success clear cannot eat a quote added mid-flight.

To let the buttons write into the composer, its draft and posting state moved up onto the tab; the draft stays keyed by pull request so switching tabs still starts with a clean box. The quote formatting is a pure helper with unit tests — validated with vp test run on the touched test file plus targeted typecheck and lint.

Note

Low Risk
UI-only comment drafting and formatting in the PR summary tab; no auth, API contract, or server changes beyond existing comment posting.

Overview
Adds quote reply on the pull request Summary tab: a hover Quote reply control on each comment (when the viewer can comment and the comment has text) inserts a GitHub-style > block into the bottom composer, focuses the textarea, and places the cursor after the quote. Quotes append under any existing draft instead of replacing it; the control is hidden while a post is in flight.

Comment composer is now controlled from PullRequestSummaryTab: draft text and posting live on the tab and are keyed by pull request URL so switching PRs does not leak drafts. Posting still uses the existing comment command and clears the draft only for the PR that was submitted.

Formatting is centralized in quoteReplyDraft in pullRequestDetail.logic.ts (line prefixes, blank line for the reply, CRLF normalization), with unit tests in pullRequestDetail.logic.test.ts.

Note

Add quote reply to pull request comments

• Adds a hover-revealed 'Quote reply' button to each pull request comment (visible when commenting is allowed, not currently posting, and the comment has content).
• Clicking quote reply inserts a > -prefixed block of the comment into the composer, focuses it, and places the cursor at the end, implemented via the new quoteReplyDraft function in pullRequestDetail.logic.ts.
• Refactors CommentComposer into a controlled component, lifting draft/posting state into PullRequestSummaryTab, with drafts now persisted per pull request URL.
• Behavioral Change: comment draft state is now keyed by PR URL, so switching between PRs preserves each PR's in-progress draft rather than sharing a single global draft.
