tressi/.github/workflows/publish.yml

A lightweight, declarative stress testing CLI for modern developers.

# ============================================
# 📦 Tressi NPM Publisher
# --------------------------------------------
# This workflow publishes the Tressi package to NPM.
#
# 🧠 Behavior:
# - Triggered manually via workflow_dispatch.
# - Checks if the version in package.json has already been published.
# - If the version is new, it builds and publishes the package.
#
# 📌 Requirements:
# - Secrets: NPM_TOKEN
#
# 🔒 Safe to run multiple times — only publishes new versions.
# ============================================
