/**
 * TerminalService - Terminal management layer above PTYSessionManager
 *
 * Manages HeadlessTerminal and VirtualTerminal instances for PTY sessions.
 * Handles dimension synchronization with active/passive modes.
 *
 * NOTE: Unlike the original, this does NOT depend on @xterm/headless or Electron.
 * Headless terminal support requires the consumer to provide an xterm factory.
 * The store sync interface is abstracted - no Electron BrowserWindow references.
