Describe the feature

Now, The template of typescript has some unnecessary lines.
The following seems a bit misleadable.

• shebang #!/usr/bin/env node in the bin file
  • The bin file is exec by ts-node, so shebang is unnecessary.
• source-map-support in the bin file
  • The bin file is exec by ts-node, so it mapped to source automatically in stack traces without source-map-support.
  • https://github.com/TypeStrong/ts-node#:~:text=Automatic%20sourcemaps%20in%20stack%20traces
• "build": "tsc" and "watch": "tsc -w" in package.json
  • It is not needed to build to .js file because ts-node can exec .ts

Use Case

This modifying make the templates simple.

Proposed Solution

• remove shebang from the bin file
• remove using source-map-support/register
• remove two npm scripts "build": "tsc" and "watch": "tsc -w" from package.json

The target of these should be app and sample-app only, not lib.
