What Problem This Solves

Agent Manager still requires an experimental opt-in to manage multiple repositories and maintains separate single-project and multi-project sidebars.

Why This Change Was Made

Use the existing project hierarchy as the only supported view. Remove the feature flag, its settings UI, and the obsolete flat sidebar, navigation, search, styles, and translations. Keep persisted state and tab-selection migration so existing sessions and worktrees remain available.

The old keyboard worktree-delete confirmation belonged to the removed sidebar. Keyboard and mouse actions now share one project-aware confirmation, including Escape and outside-click cancellation.

Project removal, legacy tab migration, background session creation, and asynchronous branch detection are project-scoped. The pinned workspace project remains protected.

User Impact

• Multi-project support is always available, even if the removed setting was previously saved as false.
• The current workspace remains the first, non-removable default project.
• Additional repositories retain their own sessions, worktrees, and sections. No repository files or worktrees need to move.

Evidence

• Full extension unit suite: 5,349 passed, 2 skipped, 0 failed across 404 files.
• Additional review regression suites: 312 focused tests passed.
• Extension build, host/webview typechecks, lint, and unused-code checks pass.
• Isolated VS Code testing with disposable repositories covers the old setting saved as false, adding and switching projects, project-targeted worktree creation, active-project removal and fallback, restart persistence, pinned-project protection, and last-project removal without a workspace folder.
• Verified keyboard delete confirmation, cancellation, collapsed-project reveal, and deletion within the correct project.
• The no-workspace empty catalog renders safely. The separate no-workspace Local/session home view remains tracked in follow-up work.
• Tests use disposable repositories and no credentials. Authenticated PR metadata and model requests were not tested.
