fix(ui): scope project session list requests (#565)

## Summary
- update @opencode-ai/sdk to 1.17.8
- load session lists through client.session.list with scope=project
- use a single high-limit project request because this endpoint does not
support cursor pagination

## Validation
- npm run typecheck --workspace packages/ui

## Notes
- Existing untracked .opencode/package-lock.json was left untouched.
