Remove the screenshot image link from the generated README.md
template as it references a non-existent asset path that would
cause broken image links in new projects. Bump version to 1.3.1.
Replace step-numbered logging with minimal ANSI-styled output
using `step`, `done`, and `fail` helpers. Consolidate redundant
README and package.json updates into a single block, remove
verbose inline comments, and simplify file creation by eliminating
unnecessary variable assignments.
