proc: the login-shell probe asks nushell through /bin/sh, and a value the shell printed instead of expanding counts as unset (#738: with nushell as the login shell, shellEnv's printf '…' "$PATH" "$CLAUDE_CONFIG_DIR" … came back as the text "$PATH", "$CLAUDE_CONFIG_DIR", … — a double-quoted string is literal in nushell — and setUnset exported every one of agentenv.Vars with its own name as the value; Claude sign-in then failed with "mkdir $CLAUDE_CONFIG_DIR: read-only file system" (putClaudeLogin's MkdirAll of that relative name under the GUI's cwd /), and the account lapsed minutes later as "Claude Code is no longer signed in", its sign-in looked for under that folder; Codex, Pi, omp and the rest were pointed at "$CODEX_HOME", "$PI_CODING_AGENT_DIR", "$OMP_PROFILE" the same way, in the GUI alone, which is the one caller of UserPath) — shellProbe builds the command: for a shell named nu it is ^/bin/sh -c '<the same printf>' (nushell has no POSIX quoting to ask with and its PATH is a list, while a child of it gets the environment as any child does, PATH joined back into one string, and sh expands the references; the outer string in nushell's single quotes where a backslash is a backslash, the format in sh's double quotes where \0 reaches printf), any other shell keeps the printf it had; and parseShellEnv takes a value that is the variable's own reference ("$CODEX_HOME", or "$PATH" for PATH) for unset, so a login shell with other quoting than POSIX leaves a variable alone rather than setting it to its name. TestShellEnvNushell runs the probe through a nushell on the machine (skipped where there is none) and checks the command's shape anyway; TestParseShellEnvUnexpanded feeds the unexpanded answer. Verified against nushell 0.116.0: PATH comes back, CODEX_HOME from the environment reaches sh, unset variables are "". (#739)
