Support missing config/input_url file

[Copilot]

Some transit agencies have no valid GTFS static URL. Currently the download script and CI jobs fail or run unnecessarily when config/input_url is absent.

Changes

• shared-opt-dir/agency-parser/download.sh: Exit early (success) if input_url is not present — skips both main download and input_url_next check. Checks both config/input_url and app-android/config/input_url (legacy "OLD REPO" path).

  if [[ ! -f "$FILE_PATH/input_url" ]]; then
      echo "> No input_url file found. Exiting early.";
      exit 0;
  fi

• shared-overwrite/.github/workflows/mt-download-data.yml and mt-check-data-outdated.yml: Added an inline Check if config/input_url file exists step right after checkout. The check covers both config/input_url and the legacy app-android/config/input_url path, consistent with download.sh. All subsequent steps in each job use an if condition so they are skipped when no input_url file is found.

  - name: Check if config/input_url file exists
    id: check-input-url
    run: |
      if [[ -f "config/input_url" || -f "app-android/config/input_url" ]]; then
        echo "has_input_url=true" >> "$GITHUB_OUTPUT"
      else
        echo ">> No input_url file found. Skipping remaining steps."
        echo "has_input_url=false" >> "$GITHUB_OUTPUT"
      fi
  
  - name: MT setup
    if: steps.check-input-url.outputs.has_input_url == 'true'
    ...

@copilot my bad, we do need to checkout the repo before checking if the file is present in the workflow files. Can we remove the new jobs created and instead add a if condition in the current job steps after checkout to check if the file is present?

Done in 5ee0064. Removed the separate check-input-url jobs from both workflow files. Each job now has a single inline Check if config/input_url file exists step right after checkout, and all subsequent steps use if: steps.check-input-url.outputs.has_input_url == 'true' to skip if the file is absent.

Code Review

This pull request introduces checks for the existence of the input_url configuration file in the download.sh script and GitHub Actions workflows to prevent unnecessary execution when the file is missing. Feedback suggests extending the file check to include legacy paths for backward compatibility and refactoring the workflow logic into a separate, lightweight job to improve efficiency and avoid repetitive step-level conditions.

@copilot as @gemini-code-assist suggested: The check for config/input_url should also include the "OLD REPO" path (app-android/config/input_url) to maintain compatibility with older repository structures, as handled in the download.sh script.

          if [[ -f "config/input_url" || -f "app-android/config/input_url" ]]; then
            echo "has_input_url=true" >> "$GITHUB_OUTPUT"
          else
            echo ">> No input_url file found. Skipping remaining steps."
            echo "has_input_url=false" >> "$GITHUB_OUTPUT"
          fi

Also update PR description to match latest code change please

Done in 1a70f01. Both workflow files now check config/input_url || app-android/config/input_url, matching the same dual-path logic in download.sh.
