+fix(create): ensure CKB binary and devnet config before generating scripts
+
+Fix issue #396 where `offckb create` failed if user hasn't run `offckb node` first.
+
+**Changes:**
+
+- Add imports for `installCKBBinary`, `initChainIfNeeded`, and `readSettings`
+- Call `installCKBBinary` to download CKB binary if not exists
+- Call `initChainIfNeeded` to initialize devnet config if not exists
+- Both calls happen before `genSystemScriptsJsonFile` to ensure dependencies are ready
+
+This makes `offckb create` self-sufficient and doesn't require prior `offckb node` execution.
