chore: carry dev.sh over — the claw+UI debug loop from the old tree

Unchanged: the paths are root-relative, so the script works as-is in
the standalone workspace.

+#!/usr/bin/env bash
+# Run the claw and the web UI together against scratch state — the quick
+# debug loop. Nothing here touches your real rhema config or sessions:
+# the daemon gets a throwaway config under $RHEMA_DEV_DIR (default
+# /tmp/rhema-dev), persisted across runs so sessions survive a restart
+# of the script; wipe the directory for a clean slate.
+#
+# Usage:
+#   scripts/dev.sh            # real provider (CLAW_DEV_PROVIDER, key from
+#                             # the provider's env var; default google)
+#   scripts/dev.sh --mock     # zero credentials: canned streamed replies
+#
+# The UI proxies /v1 to the claw, so one URL matters:
+#   http://localhost:3000
+set -euo pipefail
