WP-0039-T03: record option (b) and add silent seeding script

The founder chose to mint fresh tokens for both worker identities. Add the
reviewed, idempotent, silent script for the attended OpenBao admin lane, and
the cutover order that keeps the claim loop's gap to seconds.

+# ACTIVITY-WP-0039-T03 (option b): mint fresh ops_run worker tokens into OpenBao.
+#
+# Founder-attended only, through the silent admin lane (orientation section 5):
+#
+#   BAO_ADDR=http://127.0.0.1:18200 VAULT_ADDR=http://127.0.0.1:18200 \
+#     warden access openbao-platform-admin-login --exec -- \
+#     sh scripts/wp0039-seed-worker-tokens.sh
+#
+# Silent by design: warden fails closed on any child output. The value is
+# generated inside a pipe and sent to bao on stdin, so it never appears in
+# argv, output, Git, or the hub. Idempotent: an existing path is never
+# overwritten. Rerunning after success is a no-op that re-verifies.
+#
+# Exit codes: 0 both paths present and verified · 3 a path exists without a
+# usable token field (left untouched) · 4 write failed · 5 verification failed.
