[bug]: Local Games Missing After Upgrade to v0.6.0

### Describe the bug After upgrading to Mythic v0.6.0, none of the local games I had previously added with v0.5.0 are displayed. When I launch v0.5.0, all the games are still visible, but in v0.6.0 they no longer appear. This issue prevents me from accessing my existing local library in the latest version. ### How to reproduce 1. Launch Mythic v0.6.0 2. No local games are displayed. ### Mac & App Information Model : MacBook Pro M1 Max 32 GB RAM 32 GPU Cores | macOS 26.1 | Mythic v0.6.0 ### Logs ```bash ``` ### Before submitting - [x] I've made research efforts - [x] I've searched for existing issues
