feat: add lightweight matrix-triad-node.sh for minimal node deployments

Bash script for triad nodes without full Node.js workspace.
Usage: matrix-triad-node.sh <tm1|tm2|tm3> <send|join|sync> [args]

Uses raw curl + Python JSON — no node_modules needed.
Also: ignore heretek-openclaw-src/ (npm-publish artifact directory).
