Cockpit camera complete + namedpipe transport + 832x512 native res

Render bridge (live_bridge.py, vrview_gl.py):
- Hat glances render (left/right frame the canopy, hat-down = clean rear).
  Root bug was a stale _ckpt['fix'] key -> KeyError every glance frame ->
  render aborted (screen froze on hold, snapped back on release). The glance
  itself is the authentic eye-DCS action-0x1f reflush fp_cam already applies.
- Torso twist turret-true (root-axis yaw, zero parallax); lasers follow torso.
- Rear glance drops the canopy shell for a clean view (original-hardware
  behavior); mission-fade shroud 9fd hidden.
- Wireframe debug mode (VRVIEW_WIREFRAME / 'w' key), scene-pass scoped.
- Renderer output = 832x512, the dPL3 board's native framebuffer res.

DOSBox-X fork: namedpipe serial backend (serialnamedpipe.cpp/.h) for
vRIO/vPLASMA, replacing com0com; overlapped non-blocking I/O; typed frames
(0x00 data / 0x01 DTR+RTS). Tracked copies + apply steps in vpx-device.

Docs: COCKPIT-CAGE-NOTES (full glance/twist/rear forensics), XP-PORT-PLAN
(back-burnered), RIO-NOTES (namedpipe + keypad), pipe/egg conf variants.
