name: Split PHP SDK

# Mirrors the PHP SDK (sdk/php) into the standalone repo rmyndharis/openwa-php,
# which is what Packagist installs (Packagist needs composer.json at a repo root
# and does not support subdirectories). Uses a dependency-free `git subtree
# split` + force-push — no third-party action.
#
# IMPORTANT: this only syncs the `main` branch (-> Packagist `dev-main`). The
# monorepo's `v*` tags are the APP version, NOT the SDK version, so they are
# deliberately NOT propagated. To cut a versioned SDK release, tag the mirror
# repo directly (see sdk/php — RELEASING below), e.g. `git tag 0.1.0`.
#
# One-time setup:
#   1. Create an empty GitHub repo: rmyndharis/openwa-php
#   2. Create a PAT (fine-grained, repo = openwa-php, Contents: read & write)
#   3. Add it to THIS repo as the secret PHP_SDK_SPLIT_TOKEN
