🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Replace the placeholder metadata URI before submission.

ipfs://CID is not the published metadata CID. Governance tooling that resolves this field will not find the proposal metadata. Publish the metadata JSON and set this field to its actual IPFS CID.

Proposed fix

-    "metadata": "ipfs://CID",
+    "metadata": "ipfs://<published-CID>",
