Titles were gt-/gh-prefixed and carried the repo, which duplicates how the sidebar is already organised. Number first so it sorts, then a slug of the PR title. Routing no longer looks at the title at all -- a PR title can be edited under a running session -- and matches the worktree branch instead, covering both the head branch and the local pull/N/head one.
