# BlumeOps Release Workflow
#
# Creates a versioned release of BlumeOps with all build artifacts.
# Currently includes:
#   - Documentation site (Quartz static build)
#   - Changelog (built from towncrier fragments)
#
# Usage:
#   1. Go to Actions > Build BlumeOps > Run workflow
#   2. Enter a version tag (e.g., v1.2.0) or leave empty to auto-increment patch
#   3. The workflow creates a release with attached artifacts
#
# Documentation asset URL:
#   https://forge.ops.eblu.me/eblume/blumeops/releases/download/<tag>/docs-<version>.tar.gz
