feat(status): show the current branch's pull request, mentions and runs from the clone

tea pr status starts with the pull request of the checked-out branch,
"[feat/one] - Checks: 2 pending · Review: Approved", then lists the
pull requests created by you, assigned to you and requesting your
review under bold headings, as linked #N or OWNER/REPO#N refs with
truncated titles instead of URL columns, and "Nothing here" for an
empty section. Its JSON adds current_branch.

tea status uses the same layout, adds a Mentions section (open issues
and pull requests that mention you; JSON "mentions"), and lists the
failing runs of the clone's repository without -R, naming the remote
it came from. Piped output keeps the URLs.
