WHY IT NEEDS A POLICY

Why apply_lofi_settings needs a policy

This tool applies a preset configuration of audio effects to the project, which modifies Ableton's state reversibly. Users can undo or change settings afterward, so it is Write rather than Execute or Destructive. Severity is medium because misuse could corrupt a musical project's mix, but changes are reversible and scoped to effects settings only, not project deletion or financial impact.

From the tool's definition Tool name 'apply_lofi_settings' and description indicating bulk application of effects settings ('一括適用' = 'batch apply'). Sibling tools like 'add_effect', 'add_filter_sweep', 'add_sidechain' confirm this server modifies audio production state.
