[SPoT/Clean Code] Make transform definitions own tuning normalization and editor reset #114

Audit finding

VisualProfileCatalog exposes transform-specific tuning normalization through VisualProfileDefinition, but the profile update and editor reset paths still hard-code Soft Invert behavior:

• VisualProfileManagementService.UpdateTuning calls VisualProfileDefaults.NormalizeSoftInvertTuning(values) directly;
• VisualProfileEditorForm labels the action Reset soft profile;
• VisualProfileEditorForm.ResetValues applies VisualProfileDefaults.SoftInvertTuning directly.

This works only because Soft Invert is currently the sole editable transform. Adding another transform with SupportsTuning = true would silently normalize and reset it using Soft Invert rules.

Target state

Make the registered transform/profile definition the single source of truth for:

• tuning normalization;
• canonical/default tuning used by reset;
• supported editor adjustments, if transform-specific adjustment sets are introduced;
• transform-specific editor wording.

Keep the current catalog-based design. Do not add a second registry or a generic plugin framework.

Acceptance criteria

• VisualProfileManagementService.UpdateTuning normalizes values through the definition selected by profile.TransformId.
• The editor reset action obtains canonical tuning from the selected definition rather than directly from VisualProfileDefaults.SoftInvertTuning.
• Editor labels do not hard-code Soft Invert when editing a generally tunable profile.
• Existing Soft Invert behavior and persisted values remain unchanged.
• A test-only second editable transform proves that update and reset use its own normalization/defaults.
• Architecture documentation identifies the catalog definition as the tuning authority.

Implemented in PR #159 and merged as f7ea72f362fc865453cdc15d5dfb939df10cd4f9.

Verified checks:

• DCO run 36001402296 — success;
• full Windows build/test/release-compliance run 36001402188 — success.

The registered VisualProfileDefinition now owns canonical/reset tuning and normalization. VisualProfileManagementService.UpdateTuning resolves the target transform definition, the editor reset uses the same definition without Soft Invert wording or constants, and a test-only second editable transform verifies transform-specific normalization and reset behavior.
