fix(harness): escape every control and format character in workflow data (starter packs SP7 review P3)

The workflows data lines now escape every \p{Cc}, \p{Cf}, \p{Zl} and
\p{Zp} character by UTF-16 unit, so zero-width, soft hyphen, BOM and
tag characters never reach the prompt invisible. The section says the
rails come later in the prompt, not at its end, since skills can follow
them. A role holding task.assign or task.create only cross-role sees
every step; now tested.
