Restore stdin wait in --hidden-freeze-regression

a73x   2026-04-16 19:00

Addresses spec-review deviation: the mode should block on stdin until
the operator presses enter before spawning the waystty window, so
instructions stay visible during reading. Zig 0.15.x API:
std.fs.File.stdin().read(&buf).

Follow-up to fa7b59b.
