# semantic-release-version — compute the next semver from conventional commits
# (999_testing "semantic-release testing"). Composite action (see actions/node-build).
# Mirrors the canonical GitLab template (olsitec/gitlab ci_templates/release-automation/
# semantic-release.yaml): conventionalcommits preset + Olsitec's releaseRules, run as a
# `--dry-run --no-ci --tag-format '${version}'` probe. Outputs the computed version.
#
#   jobs:
#     version:
#       runs-on: docker
#       container: { image: foundation-ci:latest }
#       outputs: { version: "${{ steps.sr.outputs.version }}" }
#       steps:
#         - uses: actions/checkout@v4
#           with: { fetch-depth: 0 }   # REQUIRED: full history + tags
#         - id: sr
#           uses: https://forge.olsitec.net/olsitec/foundation/actions/semantic-release-version@master
#
# NOTE: dry-run version compute only (the part 999_testing checks + the GitLab
# `generate-release-version` job). Publishing a Forgejo release is deferred (no
# @semantic-release/forgejo analogue yet).
