/**
 * [WHO]: Provides TreeOverlayController + TreeOverlayContext — interactive session tree/fork/resume overlays
 * [FROM]: Depends on AgentSession/SessionManager for session lifecycle, TUI containers/components, PromptHost-like prompts
 * [TO]: Consumed by modes/interactive/interactive-mode.ts for /tree, /fork, /resume, keybindings, extension session switch
 * [HERE]: modes/interactive/controllers/tree-overlay-controller.ts — P5 tree-overlay slice (UI05, pure move + rename)
 *
 * Owns interactive session selection overlays only. It delegates reusable session lifecycle behavior to
 * AgentSession and SessionManager; it does not parse or mutate session files directly except the existing
 * rename-session callback through SessionManager.open().
