Pull request overview

Updates repo tooling to align with the latest Library.Template GitHub Actions environment conventions, particularly around when to load GitHub Actions helpers and how to propagate PATH changes in CI.

Changes:

• Only dot-source tools/GitHubActions.ps1 from tools/variables/_define.ps1 when running under GitHub Actions.
• Switch GitHub Actions PATH propagation in tools/Set-EnvVars.ps1 from writing PATH to $GITHUB_ENV to appending entries to $GITHUB_PATH.
• Add validation and a dedicated helper (Add-GitHubActionsPath) for writing to GitHub Actions’ path file.

tools/GitHubActions.ps1	Adds input validation for $GITHUB_ENV and introduces Add-GitHubActionsPath for $GITHUB_PATH.
.github/skills/bundle-dependency-prs/SKILL.md	Minor doc formatting/spelling adjustment in the skill instructions.

tools/Set-EnvVars.ps1:92

• Using GITHUB_PATH preserves the order that entries are written, but this script’s prepend loop builds PATH by prepending sequentially (and previously wrote PATH via GITHUB_ENV), which results in the final PATH order being reversed for multiple PrependPath entries. This change will alter PATH precedence across steps in GitHub Actions when more than one path is prepended. To preserve the existing behavior, write GITHUB_PATH entries in reverse order (or compute and set PATH once).

if ($PrependPath) {
    $PrependPath | % {
        $newPathValue = "$_$pathDelimiter$env:PATH"
        Set-Item -LiteralPath env:PATH -Value $newPathValue
        if ($cmdInstructions) {
            Write-Host "SET PATH=$newPathValue"
        }

        if ($env:TF_BUILD) {
            Write-Host "##vso[task.prependpath]$_"
        }
        if ($env:GITHUB_ACTIONS) {
            Add-GitHubActionsPath -Value $_
        }

        $CmdEnvScript += "SET PATH=$_$pathDelimiter%PATH%"
    }
}
