2.0.1

This maintenance release fixes unstable EDS contact identifiers that could cause duplicate contacts during synchronization.

Changes:

• Retrieve stable contact UIDs from the libebook GObject id property.
• Support alternative UID access methods across different GI binding versions.
• Avoid list-position-based identifiers whenever a stable EDS UID is available.
• Log a warning when an unstable fallback identifier must be used.
• Add regression tests for UID extraction and GI binding compatibility.
