Checklist

• This PR is small and focused
• I explained what changed and why
• I included before/after screenshots for any UI changes
• I included a video for animation/interaction changes

Note

Add environment visibility toggles to the sidebar

• Adds a globe-icon menu in the sidebar that lists environments as toggleable checkboxes; the menu only appears when more than one environment exists.
• Projects and threads in the sidebar are filtered to exclude hidden environments, while drag-to-reorder still operates on the full project ordering context.
• Visibility state is stored in sidebarEnvironmentHiddenById in uiStateStore.ts and persisted across sessions.
• Prevents hiding the last remaining visible environment to avoid an empty sidebar state.

Note

Low Risk
Client-only UI and localStorage preferences; no auth or server changes. Main edge case is navigation when the active thread belongs to a hidden environment.

Overview
Adds per-environment show/hide in the sidebar when more than one environment is configured, via a globe Environments menu with switch checkboxes (labels and project counts). Hiding an environment removes its projects and threads from sidebar lists, shortcuts, and grouping; at least one environment must stay visible.

Preferences live in sidebarEnvironmentHiddenById in uiStateStore, sanitized and persisted to localStorage. Manual project drag-reorder still uses the full project order map so hidden environments do not break reorder semantics.

MenuPopup gains an optional collisionAvoidance prop for menu positioning. resolveAdjacentThreadId now returns null when the current thread id is not in the visible list (e.g. active thread in a hidden environment).

Approvability

Verdict: Needs human review

This PR introduces a new user-facing feature allowing users to toggle environment visibility in the sidebar, with new UI components, state management, and filtering logic that changes what projects/threads are displayed. New features with runtime behavior changes warrant human review.
