Host TTY writes and ioctl updates share the inode termios cache under termiosMu. Add a field guard to enforce that existing ownership contract and replace the protection prose with the annotation.

r? @shailend-g — could you review this inode-local termios guard, given your recent host TTY lifetime work?

host_nogo could not run locally: its VDSO dependency requires Linux cross-compilers absent on this Mac. The same build failure was reproduced on the unmodified base. Linux CI is still needed to validate the annotation; no analyzer pass is claimed.

Closing in favor of consolidated #14343. The expanded replacement commits are prepared locally; the replacement branch has not been pushed yet.
