RemSound/build-release.ps1

# build-release.ps1 — produce the RemSound client release zip, and PROVE it carries
# no personal data before it can ship.
#
# Why this script exists
# ----------------------
# v1.5 and v1.6 were released with the developer's logs/, profiles/ and recordings/
# folders inside the zip — because those releases were hand-zipped from a publish/
# folder the app had been run from, which had accumulated that runtime data, instead
# of using this script. This version removes the human step that went wrong:
#   * It ALWAYS publishes into a fresh, empty staging folder — never a reused dir.
#   * It then SCANS the staged files AND the finished zip, and ABORTS (deletes the
#     zip, exits non-zero) if anything that could carry personal data is present.
# Never hand-zip publish/ again. Run this. If it aborts, the release does not ship.
#
# Usage:
#   powershell -ExecutionPolicy Bypass -File build-release.ps1 -Tag v1.7
#
# The -Tag value must match the GitHub release tag. The zip is named RemSound-<Tag>.zip
# because the in-app updater downloads exactly that asset name (AssetNameTemplate in
# RemSoundUpdater.cs: "RemSound-{tag}.zip").
