chore: fix REUSE compliance by annotating missing files in REUSE.toml

[ricogu]

Summary

Fixes REUSE compliance check failure caused by files missing copyright and licensing information.

Changes Made

• Added renovate.json to the [[annotations]] path list in REUSE.toml
• Added .claude/** to cover Claude Code worktree scratch directories

Both entries inherit the existing Apache-2.0 license and SAP copyright already applied to other config/tooling files.

Type of Change

• Bug fix (non-breaking change which fixes an issue)

Testing

reuse lint now reports full compliance:

Files with copyright information: 159 / 159
Files with license information: 159 / 159
Congratulations! Your project is compliant with version 3.3 of the REUSE Specification :-)
