/**
 * Process manager using PTY for interactive terminal execution
 *
 * Provides full terminal emulation with:
 * - ANSI color and cursor control support
 * - Real-time bidirectional I/O
 * - Terminal resize handling
 * - Interactive user input
 *
 * Used for 'interactive' and 'hybrid' execution modes.
 *
 * @example
 * ```typescript
 * const manager = new PtyProcessManager();
 * const process = await manager.acquireProcess({
 *   executablePath: 'claude',
 *   args: [],
 *   workDir: '/path/to/project',
 *   mode: 'interactive',
 *   terminal: {
 *     cols: 80,
 *     rows: 24,
 *   },
 * });
 *
 * // Listen to terminal output
 * process.onData((data) => {
 *   console.log('Terminal output:', data);
 * });
 *
 * // Send user input
 * process.write('help\n');
 *
 * // Handle exit
 * process.onExit((exitCode) => {
 *   console.log('Process exited:', exitCode);
 * });
 * ```
