Description:

Bumps rimraf from 4.4.1 to 6.1.0.

Compatibility Analysis

Breaking changes in v5-v6:

• v5: Removed default export, only named exports (affects programmatic usage only)
• v6: Requires Node.js >= 20

Impact:

• ✅ No breaking changes - rimraf used only via CLI (rimraf ./build), not programmatically
• ✅ Node.js requirement aligns - project already requires Node >= 20
• ✅ CLI interface unchanged and backward compatible

Verification:

• Build process (npm run prebuild:cleanBuildDir) executes successfully
• Full build completes without errors
• Template generation (templates/package.json.ts) remains compatible
