D1: -n/--number is the canonical record-number flag across the issue
wrappers (-i/--issue stays as alias); help text updated. D3: --labels
alias on issue-list and pr-list (-l/--label stays). Pure additive
aliases; all existing suites green (pr-list's suite arrives with the
P1b branch and will cover its alias post-merge). Survey D1-D7 now fully
closed except D5/D6 (milestone --number, uniform repo/host/login),
tracked in the plan.
