**refactor: consolidate folder structure and improve compatibility**

### Changes:
- **rollup.config.js**:
  - Merged and reformatted `nodeBuiltins` definition for cleaner code.
  - Updated `input` path from `examples/browser_compatible_exports.ts` to `demo/browser_compatible_exports.ts`.
  - Reformatted `replace` plugin configuration for better readability.

- **.github/workflows/deploy-demo.yml**:
  - Updated deployment folder from `examples` to `demo`.

- **Renamed**:
  - `examples/browser_compatible_exports.ts` → `demo/browser_compatible_exports.ts`.

- **scripts/generate-version.js**:
  - Removed unnecessary semicolons for consistent formatting.

### Purpose:
Aligned folder structure by migrating from `examples` to `demo` for uniformity and better organization. Improved code readability and formatting across configurations and scripts.
