Refs #381

TagEditor now refocuses the tag field after Add and moves the focus to the next chip's remove button (or the field) after removing a tag; CommentThread.send() refocuses the composer. The focus no longer falls to , so Esc still closes the details drawer; e2e/drawer-focus.spec.ts covers all three keyboard flows on desktop and mobile Chrome.
