Module pty 

Pseudo-Terminal (PTY) Support

Provides pseudo-terminal devices for terminal emulation and shell interaction.

Architecture

A PTY pair consists of a master and a slave side. The master is used by a terminal emulator (or the graphical desktop renderer); the slave is used by the shell or application running inside the terminal.

Data flow:

• Master writes to input_buffer → slave reads from input_buffer
• Slave writes to output_buffer → master reads from output_buffer

The PtyMasterNode and PtySlaveNode VfsNode wrappers expose these buffers as regular file descriptors so that standard read/write syscalls work transparently.
