refactor: separate PYAUTOFIT_TEST_MODE into distinct PYAUTO_* env vars

Split the catch-all PYAUTOFIT_TEST_MODE into purpose-specific variables:
- PYAUTO_TEST_MODE (sampler speedup, levels 0-3)
- PYAUTO_SKIP_FIT_OUTPUT (pre/post-fit I/O, VRAM, result text)
- PYAUTO_SKIP_VISUALIZATION (fit visualization and plotting)
- PYAUTO_SKIP_CHECKS (mesh validation, position resampling, weight thresholds)

Also renames:
- PYAUTOARRAY_OUTPUT_MODE -> PYAUTO_OUTPUT_MODE
- PYAUTO_WORKSPACE_SMALL_DATASETS -> PYAUTO_SMALL_DATASETS
