Stefan Andrei 886721d13a fix(security): guard brain-sync arithmetic against injected .brain-last-pull content; sanitize _GBRAIN_HOST
The generated preamble bash fed the raw file content of
~/.gstack/.brain-last-pull into $(( )) — bash arithmetic evaluates array
subscripts and command substitution, so a writable state file is an
execution vector. It also interpolated the gbrain host string into the
trusted status line unsanitized. Both are now normalized: .brain-last-pull
content is reset to 0 unless purely numeric, and the host is clamped to a
single line of hostname-safe characters.

Regenerated all host outputs + re-blessed ship goldens.
