Operating System

macOS

Run Mode

Electron (Desktop App)

App Version

v0.13.0

Bug Description

Max concurrency setting cannot be saved when no worktree is selected (main/primary worktree)

Steps to Reproduce

1. Open Automaker
2. Ensure you're viewing the main worktree (no feature branch worktree selected)
3. Try to change the max concurrency slider in the auto mode panel
4. The setting is not saved

Expected Behavior

Max concurrency setting should be saved even when no worktree is selected (main worktree)

Actual Behavior

The setting is not saved because the condition if (currentProject && selectedWorktree) fails when selectedWorktree is null/undefined

Screenshots

No response

Relevant Logs

Additional Context

The bug is in apps/ui/src/components/views/board-view.tsx at line 1277. The condition incorrectly requires selectedWorktree to be truthy, but it can be null/undefined when viewing the main worktree.
