Add support for SIGTTIN and SIGTTOU signals to the dirty arbiter, allowing dynamic scaling of dirty workers at runtime without restarting gunicorn. Changes: - Add TTIN/TTOU to DirtyArbiter.SIGNALS - Add num_workers instance variable for dynamic count - Add _get_minimum_workers() to enforce app worker constraints - Add signal handlers for TTIN (increase) and TTOU (decrease) - Update manage_workers() to use dynamic count - Add documentation for dynamic scaling - Add unit tests for signal handling - Add Docker integration tests The minimum worker constraint ensures TTOU cannot reduce workers below what apps require (e.g., if an app has workers=3, minimum is 3). Closes #3489
