Local-First Sync Conflict Lab 1.0.0

Initial public release.

• Rehearses three-way JSON synchronization using base, local, and remote snapshots.
• Classifies same, local-only, remote-only, and both-changed paths with JSON Pointer evidence.
• Supports manual, prefer-local, prefer-remote, and newest-snapshot strategies.
• Validates timestamps, fingerprints every input, and never touches production data.

Verified across Windows, macOS, and Linux with Python 3.10 and 3.14. CodeQL and the isolated dependency audit passed.
