Preset Edit Store

The usePresetEditStore provides isolated state for the (edit-preset) route group. It is completely separate from usePresetStore and useTaskDraftStore.

Design Decision

Preset editing must not interfere with an in-progress wizard flow. If the user is mid-way through creating a commitment, navigates to edit a preset, and then returns, the wizard state must be exactly as they left it. The isolated store guarantees this separation.

State Shape

Field	Type	Purpose
editingPreset	Preset or null	The preset currently being edited
isNew	boolean	Whether creating a new preset or editing existing
isDirty	boolean	Whether unsaved changes exist
