fix(create): ensure CKB binary and devnet config before generating scripts (#419)

* fix(create): add imports for binary installation

* fix(create): ensure CKB binary and devnet config before generating scripts

Fix issue #396 where offckb create fails if user hasn't run offckb node first.

Changes:
- Add imports for installCKBBinary, initChainIfNeeded, 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.

* chore: add changeset for issue #396 fix
