Notch 0.1.41

Notch 0.1.41 fixes local model loading, ejection and downloads.

• Downloading an Ollama or MLX model no longer mounts it or fails because free RAM changes. Existing downloads are reused. Memory and context are checked when loading.
• Mount/eject/remount operations recheck active responses after acquiring the inference lock. Stale refreshes and delayed replies cannot restore incorrect Loaded labels or select an ejected model.
• New messages wait for model-selection persistence. Loading status names the chosen model and clears after failures.
• Colibri detects engines that exit during initialization and falls back promptly. Strata refuses to switch when its control runtime reports an unsuccessful stop.
• Background Windows servers and shell supervisors avoid detached consoles, while background commands retain output and survive closing the IDE.

Validation: 381 automated tests and strict type checking pass. Packaged download UI checks cover light/dark themes, low-memory warnings, progress, cancellation and retries. Real Colibri load/eject checks on Radeon 8060S pass using CPU fallback after Vulkan initialization fails. The existing Nimbus 4B download was recovered from cache without generation.

GPU speed benchmarks were skipped. Strata has no installed weights on the test PC; its hardware catalog and fixture-based switching/stop tests pass, while live weight loading remains unverified. Existing chats, settings and model files are retained.
