fix(sidebar): let sidebar parent rows open the main worktree explicitly

Upstream now restores the last selected linked worktree when reselecting a repository, which is useful for normal repo switching but conflicts with the sidebar parent-row interaction. After visiting a synthetic child row, clicking the parent row should open the parent repository itself instead of bouncing back into the remembered worktree.

Changes:
- add an explicit `followPreferredWorktree` selection flag through dispatcher and app-store repository selection paths
- keep the upstream preferred-worktree restore behavior enabled by default for existing selection flows
- make repository sidebar row clicks opt out of preferred-worktree restoration so an explicit parent-row click opens the main worktree

Behavioral effect:
When a user clicks a repository parent row in the sidebar after visiting a linked worktree, the app now opens the parent repository directly instead of restoring the previously selected child worktree behind the user's back.

Testing:
- yarn eslint app/src/ui/dispatcher/dispatcher.ts app/src/lib/stores/app-store.ts app/src/ui/app.tsx
- yarn compile:prod
