fix(deps): bump shell-quote to 1.8.4 (GHSA-w7jw-789q-3m8p)

Patches the critical shell-quote advisory (quote() does not escape
newlines in object .op values, CVSS 8.1). shell-quote is a dev/build-only
transitive dependency (react-dev-utils / launch-editor) and is not present
in the production image or the browser bundle, so there is no runtime
exposure; this clears the alert and the dev-time risk. Lockfile-only change
verified to install with shell-quote resolving to 1.8.4.
