feat: refactor protocol configuration handling in main and plugin

- Add protocol configuration to the `run` function in `main.go`
- Remove redundant protocol configuration from the `run` function in `main.go`
- Add proxy protocol configuration to the `run` function in `main.go`
- Add protocol configuration to the `removeAllDestFile` function in `plugin.go`
- Add proxy protocol configuration to the `removeAllDestFile` function in `plugin.go`
