feat: add fallback to pretend_list in plan_next_actions logic

Extend the decision flow in `plan_next_actions` to consider the `pretend_list` when no suitable
target is found in `regard_list` within the 10‑unit time threshold. The new fallback selects a
destination from `pretend_list` if its travel time is under 8 units, improving target
selection robustness.
