Test suite modernization: pytest wrapper and runner fixes

- Add LD_LIBRARY_PATH auto-configuration in run_tests.py
- Add --timeout and --quiet command-line flags
- Create pytest wrapper (conftest.py, test_mcrogueface.py) for IDE integration
- Configure pytest.ini to avoid importing mcrfpy modules
- Document known issues: 120/179 passing, 40 timeouts, 19 failures

+# McRogueFace Test Suite - Known Issues
+
+## Test Results Summary
+
+As of 2026-01-14, with `--mcrf-timeout=5`:
+- **120 passed** (67%)
+- **59 failed** (33%)
+  - 40 timeout failures (tests requiring timers/animations)
+  - 19 actual failures (API changes, missing features, or bugs)
+
+## Timeout Failures (40 tests)
+
+These tests require timers, animations, or callbacks that don't complete within the 5s timeout.
+Run with `--mcrf-timeout=30` for a more permissive test run.
+
+**Animation/Timer tests:**
+- WORKING_automation_test_example.py
+- benchmark_logging_test.py
+- keypress_scene_validation_test.py
+- simple_timer_screenshot_test.py
+- test_animation_callback_simple.py
+- test_animation_property_locking.py
+- test_animation_raii.py
+- test_animation_removal.py
+- test_empty_animation_manager.py
+- test_simple_callback.py
+
+**Headless mode tests:**
+- test_headless_detection.py
+- test_headless_modes.py
+
+**Other timing-dependent:**
+- test_color_helpers.py
+- test_frame_clipping.py
+- test_frame_clipping_advanced.py
+- test_grid_children.py
+- test_no_arg_constructors.py
+- test_properties_quick.py
+- test_python_object_cache.py
+- test_simple_drawable.py
+
+## Running Tests
+
+```bash
+# Quick run (5s timeout, many timeouts expected)
+pytest tests/ -q --mcrf-timeout=5
+
+# Full run (30s timeout, should pass most timing tests)
+pytest tests/ -q --mcrf-timeout=30
+
+# Filter by pattern
+pytest tests/ -k "bsp" -q
+
+# Run original runner
+python3 tests/run_tests.py -q
+```
+
+## Recommendations
+
+1. **For CI:** Use `--mcrf-timeout=10` and accept ~30% timeout failures
+2. **For local dev:** Use `--mcrf-timeout=30` for comprehensive testing
+3. **For quick validation:** Use `-k "not animation and not timer"` to skip slow tests
