Backend (prs.go):

Update — PATCH /{prID} edits title and/or body, validates title non-empty, returns prWithReviewers
Reopen — POST /{prID}/reopen transitions closed → open, fires webhook
Close now returns prWithReviewers and fires a webhook
Merge already existed; no changes needed
Frontend — PRDetailPage.tsx full rewrite:

Inline title editing — pencil icon (visible to author/admin when open), Enter to save, Esc to cancel
Inline body editing — same pattern in the description panel
Merge sidebar — radio buttons for allowed strategies (fetched from repo's merge strategy settings), "Merge pull request" button in Bitbucket purple, "Close without merging" below it
Status banner — merged (purple) or closed (grey) with the date, shown below the description
File list — scrollable +N −N table above the diff viewer showing all changed files with addition/deletion counts
Reopen button — appears in the sidebar when the PR is closed
Reviewers panel — lists assigned reviewers with avatars/initials
Details panel — from/into branches, opened date, last updated
Quick links — back to all PRs, open new PR
PRsPage.tsx — now shows real data:

Two tabs: "My pull requests" and "Awaiting my review" (with live counts from dashboard)
Per-repo quick links at the bottom showing open PR count badges
