v0.49.1 - Text-Safe Vision Upgrades
This patch keeps existing text-only installations usable after optional vision metadata is added and restores the selected model's manifest context instead of retaining a stale 4,096-token backend.
Highlights:
- Legacy schema-v1 registries remain valid for startup and ordinary text conversation.
- Projector download and binding happen only on first image use.
- Exact projector caches are reused and registry evidence is preserved during atomic v2 migration.
- Projector preparation failures preserve the selected model, text-ready backend, default selection, and registry.
- Model setup no longer eagerly downloads optional multimodal artifacts.
- Candidate preflight now enforces model-upgrade compatibility regressions.
GitHub Releases remains the only supported binary distribution channel.
