Notch 0.1.45

Notch 0.1.45 improves local-model setup and switching, and introduces a diamond-shaped task menu with new icons and slim gray download progress bars.

• Colibri setup, validation, cleanup and queued model loads now share the same inference lock.
• Context changes finish checking memory and saving before a queued model can load.
• Strata folder changes cannot alter an active download after a delayed folder-picker response. Late cancellation restores the previous model selection while retaining downloaded files.
• Installers refresh their runtime dependencies from the tested build. Security updates cover fast-uri, undici and constrained Zod collection parsing; the legacy Zod 3 API is retained with a documented compatibility patch.

Verification uses the real Colibri 2.0.0 and Strata Control 0.1.47 processes with tiny test engines, including launch, eject, remount, switching, failed startup and retry. No large model downloads or GPU benchmarks are required. Full-weight GPU inference across every hardware configuration is outside this release's verification scope.

The update keeps the existing application identity, settings, chats and model locations. Windows x64 installer; unsigned. See the repository's release-readiness document for the audit findings and verification limits.

Final verification: 418 source tests passed, strict typecheck and core build passed, packaged UI checks passed in both themes, and the installed app passed Colibri and Strata lifecycle checks with zero observed console windows. Settings and chats remain unchanged. No model downloads or benchmarks were run.
