Version number hardcoded as `"v1.0.0"` in CLI banner

[MadhushaPrasad]

Description:
The intro banner in script.ts hardcodes the string v1.0.0. When the package version is bumped in package.json, the banner shown to end-users will stay out of date. The version should be read dynamically from package.json.

File: script.ts

Expected: Import and use the version field from package.json (via resolveJsonModule) so the banner always reflects the published version.
