License Migration to Apache 2.0

The OSPO is driving a strategic relicensing of ownCloud repositories toward the Apache License 2.0, following the Apache Software Foundation's third-party license policy.

Individual repositories will migrate as their audit is completed. The LICENSE file in each repo reflects its current license status (not the target).

Current license: GPL-2.0 (Category X per Apache policy -- cannot be included in Apache-2.0 works).

Migration prerequisites for this repository:

• CLA/DCO coverage: All past contributors must have signed agreements permitting relicensing
• Copyleft dependency audit: All GPL dependencies must be replaced or isolated
• KDE heritage review: Any code with KDE-era copyrights requires legal analysis
• Complete relicensing: GPL-2.0 is a strong copyleft license; migration requires full relicensing of all files
