Ship Meshtastic Chat UX, embedded Infonet/SHELL panels, and Docker dev polish.

Rename Mesh Chat to Meshtastic Chat, embed the Infonet terminal with Arti/Tor warmup, improve the agent shell PTY (git in the backend image, operator PATH), and add docker-compose.override for local image builds. Gitignore Hermes Agent runtime installs.
