Description

Add copyright and SPDX license headers to all shell scripts (.sh files) in the repository. This is a quick task with only 5 files, ideal for a new contributor to familiarize themselves with the codebase structure.

Acceptance Criteria

• Add headers to all 5 shell scripts listed below
• Headers placed immediately after the shebang line
• Scripts remain executable and functional
• No syntax errors introduced

File List

Implementation Steps

1. For each file, insert the following header after the shebang line:

   #!/bin/bash
   # Copyright (c) Microsoft Corporation.
   # SPDX-License-Identifier: MIT

2. If a file has no shebang, add both the shebang and the header

3. Verify scripts remain valid:

   bash -n scripts/dev-tools/pr-ref-gen.sh

Example Before

#!/bin/bash
set -euo pipefail
# Script content...

Example After

#!/bin/bash
# Copyright (c) Microsoft Corporation.
# SPDX-License-Identifier: MIT

set -euo pipefail
# Script content...

Time Estimate

30 minutes
