UIL-X v0.6.0: P2P Mesh Gossip & ROS2 Emergency Stop Integration

v0.6.0 introduces distributed multi-node safety interlocks, zero-configuration UDP mesh discovery, and native ROS2 motor override bindings.

🌐 What's New in v0.6

P2P Mesh Gossip Network (pkg/mesh):
- Auto-discovers cluster peers (deepn-node-1, deepn-node-2, Pi Zero edge nodes) via UDP port 9090.
- Propagates high-priority interlock breach payloads across nodes with sub-second latency.
ROS2 Emergency Stop Bridge (ros2/):
- Exposes non-blocking Unix Domain Socket IPC streaming (/tmp/uild.sock).
- Publishes boolean $E\text{-}Stop$ signals (/safety/emergency_stop) and zero-velocity overrides (/cmd_vel) to halt autonomous robotics hardware upon interlock breach.
Live Kernel Telemetry (pkg/substrate/gpio_linux.go):
- Reads CPU thermal zones directly from Linux sysfs (/sys/class/thermal/thermal_zone0/temp).
Continuous Daemon Execution:
- Updated uild run into a long-running background daemon with OS signal interception (SIGINT/SIGTERM) and continuous $UPFo$ SHA3 payload commitments.
