refactor: prefix two collision-prone helpers, document naming audit

Two owned helpers carried unprefixed generic names that risk colliding in the single Emacs namespace: car-member (local-repository.el) and unpropertize-kill-ring (system-defaults.el). I renamed them to localrepo--car-member and cj/--unpropertize-kill-ring and updated their callers and tests. Both are non-interactive and contained, so no alias was needed.

docs/design/naming-audit.org records the rest of the scan: the allowlist of deliberate module prefixes, the foreign forward-declarations that aren't owned definitions, and a deferred list (keybound commands, the with-timer macro, the ui-theme defcustoms, the user-constants paths) that each want a focused pass rather than an unattended rename.
