# Promote Release - Prepare Release Branch for Production
# =============================================================================
#
# Purpose: When QA approves an RC, this workflow prepares the release branch
# for production by removing the -rc suffix from version numbers.
#
# IMPORTANT: This workflow does NOT merge the PR (org rules prevent bot merges).
# Instead, it updates the release branch so when a human merges, the version
# is clean (e.g., 6.18.0 instead of 6.18.0-rc1).
#
# Flow:
# 1. QA tests the RC version
# 2. QA adds label "pass QA ready for deploy" to the PR
# 3. This workflow triggers and:
#    - Verifies rc-smoke/npm check-run is green
#    - Strips -rcN from all version files
#    - Commits changes to the release branch
# 4. Human reviews and manually merges the PR
# 5. release.yml triggers on merge (production path)
