The agent now drives the matrix in <1s via the resident responder instead of
compiling+flashing a sketch (~95s). Pieces:
- matrix-relay/: a tiny container (python-apps-base) running relay.py — a
TCP:9999 → RouterBridge relay. The ZeroClaw daemon runs on the host for
hardware access, but the RouterBridge python binding (arduino.app_utils)
only ships in the App Lab image, so JUST the relay runs containerized,
mounting the router socket + publishing :9999 to loopback.
- config.template.toml: add matrix_pattern + matrix_text to the default risk
profile's allowed_tools/auto_approve (the capability filter hides tools not
listed — this was why matrix_text wasn't exposed to the agent).
- skills/led-matrix: lead with "use matrix_text / matrix_pattern first"; only
flash for custom frames (flashing overwrites the responder). NOTE skills load
from each agent's workspace copy, not shared/skills — push to all workspaces.
- provision-host-daemon.sh: flash the responder once + start the relay.
Proven on-hardware: "show a heart" and "scroll GO CLAWS" both instant via the
agent, no flash.
