Replace the limit-driven auto-walking Paginate helper with explicit
cursor-pagination flags (--first/--after, --last/--before) that mirror
the GraphQL connection arguments. List commands now return a single
keyset page with its page info, and emit cursors so callers can page
forward and backward. --before no longer requires --last: both --first
and --last default to 50 when omitted.
Also split the tracker-pattern stats into enriched with and without a
description so the enrichment backlog is visible at a glance.
