Documentation and lock file inconsistency: pnpm vs npm in install instructions #29

Current Behavior

The repository provides a pnpm-lock.yaml file suggesting pnpm is used, but the README.md and README.template.md use npm (e.g., 'npm install'). This may be confusing for users and could lead to mixed package managers.

Reproduction / Steps To Reproduce

1. Open the root directory and see pnpm-lock.yaml present.
2. Read the install instructions in README.md and README.template.md for 'npm install'.
3. Attempt to use both npm and pnpm, resulting in mixed or unexpected dependencies.

Anything else?

Recommended solution: Remove pnpm-lock.yaml and use npm for consistency, since the docs standardize on npm. Optionally, re-create a lockfile with 'npm install' after removing pnpm-lock.yaml.
