Interactive claude session hung silently after
`attaching interactive claude session...` — `runuser -l` invokes
a login shell that triggers PAM session setup / /etc/profile
sourcing, and the minimal Debian agent VM doesn't have the PAM
config files for that to complete cleanly. claude never got to
draw its TUI.
Switch UID via plain `runuser -u <user> --` (no `-l`) and inject
HOME / USER through `smolvm machine exec -e` so the child
process sees them. Avoids login-shell wiring entirely. Same
pattern in `exec_claude` and `exec(script)`.
`_HOME_FOR` maps the two users the codebase currently asks for
(`node`, `root`); anything else falls back to `/home/<user>`.
