fix(ci): make npm run ci --full actually run the full gate

scripts/ci-local.sh gated its two storybook + axe steps on
`[[ "${1:-}" == "--full" ]]`, so the flag had to arrive as a positional
argument. CLAUDE.md documents `npm run ci --full`, but npm parses that
flag itself and exports `npm_config_full=true` instead of passing it
through. Proven with `npm run env --full`.

The documented command therefore skipped both steps and still printed
"local CI passed" — a gate that reported success without running. Anyone
following CLAUDE.md has been skipping storybook-a11y.

Accept either form. Fixing the script makes every existing document
correct, instead of changing four of them and re-teaching the reader.

Found while verifying RD-06, which adds stories and so depends on those
steps actually running.
