GitAuto: token_output is always 0

[gitauto-for-dev]

Resolves #12387

Why the bug occurs

The token_output variable is incorrectly initialized to 0 in main.py and is not being updated properly during the execution flow. This causes the output to remain 0 regardless of the intended operations that should modify its value.

How to reproduce

1. Clone the repository and navigate to the project directory.
2. Ensure all dependencies are installed by running pip install -r requirements.txt.
3. Execute the application using python main.py.
4. Perform operations that are supposed to modify token_output (e.g., processing input tokens).
5. Observe that the token_output remains 0 despite the operations.

How to fix

• Initialization: Update the initialization of token_output in main.py to ensure it starts with an appropriate value based on the application's logic.

  # Before
  token_output = 0
  
  # After
  token_output = initial_token_value  # Set to a meaningful initial value

• Update Logic: Review and modify the functions responsible for updating token_output to ensure they correctly modify its value based on the application's operations.

  def process_tokens(tokens):
      global token_output
      for token in tokens:
          # Correctly update token_output based on processing
          token_output += compute_token_value(token)

• Testing: Add unit tests in the tests directory to verify that token_output is being updated correctly during various operations.

  def test_token_output_update():
      initial_output = token_output
      process_tokens(['token1', 'token2'])
      assert token_output > initial_output

By addressing the initialization and update logic of token_output, the variable will reflect the correct value based on the application's workflow.
