fix(cli): remove @o2s/framework refs from .storybook/main.ts during scaffold

[ysdy823]

Summary

Fixes #836

After scaffolding with create-o2s-app, Storybook fails because .storybook/main.ts still contains references to @o2s/framework/sdk and @o2s/framework/modules in both resolve.alias (lines 92-93) and optimizeDeps.include (lines 76-77), even though packages/framework/ is removed during scaffolding (listed in ALWAYS_REMOVE_DIRS).

Changes

• New file: packages/cli/create-o2s-app/src/scaffold/transform-storybook-config.ts — a transform that filters out lines containing @o2s/framework/ references from .storybook/main.ts
• Modified: packages/cli/create-o2s-app/src/scaffold/index.ts — added transformStorybookConfig to the Step 4 parallel transform batch

The transform follows the same regex-based line-filtering pattern used by existing transforms (e.g., transform-app-module.ts).

Test plan

• Run npx create-o2s-app and scaffold a project
• Verify .storybook/main.ts in the scaffolded project does not contain @o2s/framework references
• Verify Storybook starts correctly with npm run storybook

• New Features
  • Project scaffolding now automatically updates Storybook configuration during creation, removing legacy framework-specific references to ensure a cleaner, compatible setup.
