fix(audit): exclude retired projects from the sync target list

The audit's project discovery uses find -maxdepth 3, which reaches ~/projects/.retired/<name>/.ai — one level deeper than a live project — so shelved projects were getting template syncs they should never receive. Skip any project under a .retired/ ancestor explicitly, so the exclusion holds regardless of the find depth.
