fix(#624): read codex's trust prompt as BLOCKED when it ends in esc back

On codex-cli 0.162.0, with 0.163.0 released, every launch first shows the
"Update available" prompt, and choosing Skip leads to a variant of the
workspace trust prompt: "2. Back to Agent Command Center" over the key-hint
row "enter continue · esc back". The pattern only accepted cancel,
interrupt, quit, answer or all as the closing word, so a fresh git repo
launched from Codeman sat on that trust prompt reading idle, with no red
alert and no blocked signal (measured live on a throwaway instance).

Adding "back" is safe because the hint row must still START with one of
the anchored hints ("enter continue" here): the popups the user opens at
the keyboard (/model, /permissions, /review, Implement this plan?) end in
"esc back" too, but their row starts with "enter select", so they stay
unmatched, as every existing negative fixture confirms. The new fixture is
the live capture with the scratch path replaced.
