refactor(task): relocate map_task_synonym to loader.task as to_optimum_task#801
Merged
Conversation
…m_task Establish a single WinML->Optimum task collapse boundary in loader/task.py. map_task_synonym and TASK_SYNONYM_EXTENSIONS move from export/io.py to loader/task.py as to_optimum_task; export.io keeps map_task_synonym as a backward-compatible alias. Optimum-boundary call sites (inspect command, HTP exporter, inspect resolver) call to_optimum_task directly. No behavior change. Part of #800.

No behavior change.
map_task_synonymstays importable fromexport.io; the collapse semantics (image-feature-extraction->feature-extraction, WinML extensions preserved) are byte-identical. Existing synonym and #777/#782 regression tests stay green.Sets up PR2 (#800), which adds the modality-aware
detect_taskand relies on this single collapse boundary.
