研究方向

This issue requests a decorator that checks if a TCP port is free before running a test. The current codebase uses decorators like `@expect.raises`; examine the existing decorator pattern in the sure library (e.g., in sure/ init .py or decorators.py). Implement a new decorator `@expect.free port(port)` that uses Python's socket module to attempt binding to the port and skip or fail the test if busy. The issue has an assignee but no recent activity, so confirming availability with maintainers may be needed before starting.
