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.
