fix: use consistent claude path and add DISINTO_CONTAINER=1 to edge service

- Replace hardcoded versioned path with /usr/local/bin/claude:ro, matching
  all other services (agents, agents-llama) so claude auto-updates don't
  silently break the edge container
- Add DISINTO_CONTAINER=1 so lib/env.sh routes DISINTO_LOG_DIR to the
  persistent disinto-logs volume instead of the ephemeral git clone; this
  ensures supervisor-run.sh log() calls survive container restarts
