fix(statusline): unset a stale user statusline var, write the exporter script atomically

Three small follow-ups from the #361 review.

A tmux setenv survives respawn-pane, so _configureStatusLineUserCommand
returning early when the user has no statusline left a previously
exported CODEMAN_USER_STATUSLINE_CMD in place: a user who deleted their
own statusline kept getting the stale one wrapped, and lost Codeman's
footer print-through, until the tmux session was recreated. It now
issues `setenv -u` in that case, the same shape as the effort-level
cleanup in applyEnvOverrides.

ensureStatusLineExporterScript truncated and rewrote a script that live
sessions execute on every statusline render, and chmod'd it after the
write. It now writes a temp file next to the target, chmods that, and
rename()s it into place.

The non-tmux direct-PTY fallback carries no exporter; that is now stated
at the spawn site and in the architecture-invariants paragraph rather
than left as a silent gap.
