The Small Model override chosen in Settings never reached the managed
OpenCode process config, so OpenCode's own title/summary generation
kept using its fallback chain instead of the user's explicit choice
and sessions stayed untitled.
Merge main into this branch to pick up the includeWeb/includeMemory
flags added to prepareManagedOpenCodeEnv, and re-apply the Small
Model injection on top of that current env shape in
getManagedOpenCodeEnv (server/index.js).
Closes#2497
