feat(rumpk): Implement PTY subsystem for terminal semantics
Phase 40: The Soul Bridge
IMPLEMENTED:
- PTY subsystem with master/slave fd pairs (100-107 / 200-207)
- Ring buffer-based bidirectional I/O (4KB each direction)
- Line discipline (CANON/RAW modes, echo support)
- Integration with FB terminal renderer
CHANGES:
- [NEW] core/pty.nim - Complete PTY implementation
- [MODIFY] kernel.nim - Wire PTY to syscalls, add pty_init() to boot
DATA FLOW:
Keyboard → ION chan_input → pty_push_input → master_to_slave buffer
→ pty_read_slave → mksh stdin → mksh stdout → pty_write_slave
→ term_putc/term_render → Framebuffer
VERIFICATION:
[PTY] Subsystem Initialized
[PTY] Allocated ID=0x0000000000000000
[PTY] Console PTY Allocated
REMAINING: /dev/tty device node for full TTY support
