把 target-ip 改为 listen host，这个导致很多误解

This issue has no description.

The issue provides no files, tests, or implementation details; begin by searching the repository for `target-ip` and related configuration or documentation references. Determine the affected entry points and tests before changing the terminology, and consider the work complete when the old name is consistently replaced with `listen host` without breaking existing behavior.
