Subject: [PATCH] fix(build): prune stale generated api endpoints

Clean list-specific JSON endpoint directories before rewriting them so local and deploy-style API builds do not fail on leftover files from older runs.

Keep the count check, but count only generated JSON outputs so the verification reflects the actual endpoint set.
