# Build the VS Code extension from a FROZEN release branch and attach a
# SHA256-verified `.vsix` to a DRAFT GitHub release. Triggered manually
# (workflow_dispatch) with the target version; it checks out the
# `release/vscode-v<version>` branch (created by vscode-release-pr.yml) rather
# than main, so the built artifact is frozen to that branch — commits that land
# on main after the release branch was cut cannot leak into the release. The
# `vscode-v<version>` tag is created on the branch commit when the draft is
# published. The version comes from the branch's `package.json` (verified to
# match the input), so the tag and the packaged version can't diverge.
#
# This produces the ARTIFACT ONLY — it does NOT publish to the VS Code
# Marketplace or Open VSX. That runs from the central secure-release repo
# (databricks/secure-public-registry-releases-eng), on hardened runners, where
# a workflow downloads this `.vsix`, verifies its `.sha256`, scans it, and
# publishes. Keeping the two halves separate is deliberate: this job only
# builds and uploads; the secured half holds the marketplace tokens and scan
# gate.
#
# The release/tag is named `vscode-v<version>`, a dedicated namespace kept
# separate from the Python release tags (`v[0-9]*`) consumed by
# github-release.yml.
