When a predefined agent has an operator-authored USER_PREDEFINED.md, the
built-in per-user USER.md template is no longer seeded or injected into the
system prompt. This gives operators full control over user-context in the
prompt and stops the per-turn name/timezone profile nag. Open agents and
predefined agents without USER_PREDEFINED.md are unaffected.
