Lightweight 17375-only republish: skip 7375 rewrite, no deletions needed

Kind 17375 is a replaceable event (NIP-60, d-tag=''), so publishing a new
one automatically supersedes the old one on relays. The republish now only:
1. ensureDirectNutzapP2pk() - generate privkey if missing
2. Build NIP-60 tag-array payload
3. NIP-44 encrypt + sign + publish single 17375 event
That's 1 signing round-trip instead of 100+.
Reduced timeout from 120s back to 30s.
Bumped WORKER_REVISION to nip60-lightweight-republish-1.
