fix(avoidance): expand detection area to prevent chattering

[satoshi-ota]

Description

🤖 Generated by Copilot at 5d511c7

Improved the object avoidance logic in the behavior path planner by adding a flag to indicate the module status and expanding the detection area width accordingly. Modified the separateObjectsByPath function in utils.hpp and utils.cpp to accept and use the flag.
