When the forgejo_event_path input is not supplied, WUMING_EVENT_PATH in the action.yml env block resolved to "" and GITHUB_EVENT_PATH was not automatically inherited by the Docker container. This left pr_index empty on genuine pull_request events, causing WuMing to exit immediately with 'nothing to review'.
Fix: use ${{ inputs.forgejo_event_path || github.event_path }} so the runner-provided event path is used when the caller omits the input.
Closes #47
