Automatically copies `.env.example` from the installed `@zen/core`
package to `.env` in the project root if it doesn't already exist.
This removes the need for users to manually locate and configure
environment variables. Updated the post-install instructions to
reflect the new behavior.
Remove the `experimental.instrumentationHook` option from the generated
`next.config.mjs` template, as it is no longer needed in newer versions
of Next.js. Bump package version from 1.3.1 to 1.3.2.
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.
