Merge branch 'main' into merge/main-into-dev

Brings in 8 main commits (0.1.48 release, provider overhaul, keyboard
shortcuts, desktop login shell env, question form Enter key) with proper
git history. Resolves conflicts by keeping dev branch architecture where
it subsumes main's changes, and main's provider snapshot COMPAT comments.
