fix(opencode): hide common config snippet UI and prevent auto-merge

- Add `enabled` parameter to useCommonConfigSnippet hook
- Skip all loading and auto-merge logic when enabled=false
- Replace CommonConfigEditor with simplified JsonEditor for OpenCode
- Prevent Claude's common config snippet from being injected into OpenCode
