将 unittest.main() 移到文件末尾。

直接执行此文件时，unittest.main() 会在 TestQuoteRefPathWire 定义前运行。该执行方式不会运行新增的 ref 路径回归测试。将此块移到所有测试类之后。

block containing unittest.main() to the end of
tests/test_github_backend_wire.py, after the TestQuoteRefPathWire class and all
other test definitions, so direct execution discovers and runs the regression
tests.

Remediation recommended

1. Late test class skipped 🐞 Bug ≡ Correctness

tests/test_github_backend_wire.py calls unittest.main() before defining TestQuoteRefPathWire, so
running this module directly will not execute the ref-prefix regression test. This can silently
reduce coverage in workflows that execute test files as scripts.
Agent Prompt 
### Issue description
`unittest.main()` is executed before `TestQuoteRefPathWire` is defined, so `python tests/test_github_backend_wire.py` will not run that test class.

### Issue Context
This file is a regression test meant to lock request shapes and ref path quoting behavior. It should execute all test classes when run directly.

### Fix Focus Areas
- tests/test_github_backend_wire.py[65-77]

### Suggested change
Move the `if __name__ == "__main__": unittest.main()` block to the end of the file (after `TestQuoteRefPathWire`), or move `TestQuoteRefPathWire` above the block.
