chore(license): Add SPDX-License-Identifier to LICENSE.md

[tintinhamans]

Adds SPDX-License-Identifier: GPL-3.0-or-later as the first line of LICENSE.md so GitHub (and other third-party) license detectors can recognize the license.

It was previously not auto-detected because of the additional EA terms appended after the standard GPLv3 text.

Add SPDX identifier to GPLv3 license

📝 Documentation 🕐 Less than 5 minutes

AI Description

• Adds the GPL-3.0-only SPDX identifier to the license file.
• Enables automated license detection despite the appended Electronic Arts terms.

High-Level Assessment

The SPDX identifier is the standard, minimal solution for improving automated license detection without modifying the existing GPLv3 text or additional terms.

Declare the GPL-3.0-only SPDX license identifier

• Adds an SPDX license identifier at the beginning of the file so GitHub and other tools can recognize the repository license despite the appended terms.

[greptile-apps]

Greptile Summary

Updates the SPDX header in LICENSE.md from GPL-3.0-only to GPL-3.0-or-later.

• Leaves the previously reported incomplete representation of EA’s additional Section 7 terms unresolved.
• Also labels the GPL component as “or later,” although the license notice describes GPL version 3 without granting the later-version option.

Confidence Score: 4/5

The PR is not safe to merge until the SPDX declaration accurately represents both the GPL grant and EA’s additional terms.

The previous blocking finding remains outstanding. The new identifier still omits EA’s additional Section 7 terms, and changing the GPL component to GPL-3.0-or-later introduces a later-version grant that the document’s GPL version 3 notice does not state.

Files Needing Attention: LICENSE.md
