The registerGroup() function in index.ts creates the group folder and
logs subdirectory but never copies the global CLAUDE.md template.
Agents in newly registered groups start without identity or
instructions until the container is manually fixed.
Copy groups/global/CLAUDE.md into the new group folder on registration,
substituting the assistant name if it differs from the default.
Closes#1391
The example "1234567890" was ambiguous — users couldn't tell where the
country code ended and the number began, and some included a leading "+"
which caused pairing to fail. Use a realistic US example (14155551234)
and explicit formatting rules in both the prompt and troubleshooting.
Closes#447
