Notch 0.1.43

Notch 0.1.43 improves local-model recovery and retains the download/mount/eject fixes from 0.1.42.

• Show loading dots above the composer during model discovery, mounting and ejecting; reconcile the catalog before clearing loading, and retain real failure messages. The composer controls stay mounted when status appears or disappears.
• Count shared GPU allocations above physical VRAM as reclaimable system RAM when switching models, including integrated Radeon setups.
• Improve Colibri/Strata text spacing, backend explanations, wrapping, model-row layout and keyboard navigation.
• Cancelled Colibri and Strata setup/download jobs stay cancelled even if their underlying operation finishes at the same moment. A new attempt can complete normally.
• Local CLI operations have a bounded deadline. Discovery uses a one-minute limit; confirmed file downloads have up to 24 hours. Timeout errors retain downloaded files and support retry.
• Regression checks cover failed startup and remount, rejected overlapping changes, failed eject, release-before-load ordering, cancellation with inherited helper output, and timeout/retry.

Validation: 397 automated tests and strict type checking pass. Release checks include the exact packaged modules, renderer loading/error/retry/eject states, installed Ollama model load/eject/remount/switch using two entries that share existing weights, profile/model preservation, Windows console visibility, and public installer/updater checksums.

Settings, chats, downloaded models and application identity are preserved. No large Colibri/Strata models are downloaded for testing, and no speed benchmarks are run. The official Strata catalog recognizes the Radeon 8060S through AMD HIP, but no offered model fits the current free memory on the test PC, so real loaded Strata eject/switch remains unverified. Live NVIDIA/macOS/Linux execution remains unverified.
