<#
.SYNOPSIS
  Upload pre-built NSIS artifacts to a Gitea release.

.DESCRIPTION
  Uploads installer + blockmap + latest.yml to the release identified by -Tag.
  If the release does not exist it is created (only for semver-looking tags;
  for non-semver tags like 'update-channel' the release must exist already).
  Same-named existing assets are replaced.

.PARAMETER Tag
  Release tag to upload INTO. May be a version tag (v0.5.1) or a channel
  tag (update-channel). Defaults to v<package.json version>.

.PARAMETER AssetVersion
  Version of the artifacts being uploaded (e.g. 0.5.1). Defaults to the
  numeric part of -Tag. Specify explicitly when uploading version-X.Y.Z
  artifacts into a non-version tag (channel or bridge).

.EXAMPLE
  pwsh scripts/upload-release-assets.ps1
  pwsh scripts/upload-release-assets.ps1 -Tag v0.5.0
  pwsh scripts/upload-release-assets.ps1 -Tag update-channel -AssetVersion 0.5.1
  pwsh scripts/upload-release-assets.ps1 -Tag v0.4.0 -AssetVersion 0.5.1
