scope: Tool-panel hosts and image app fixes

Context

Reusable interaction tools were being attached to generic empty sections, while several image apps had separate problems with file-entry identity, reported output size, and White ROI updates.

Decision and rationale

Add a semantic toolPanel host for composed tools and fix the image-app behaviors at their actual data owners. Normalize file entries and regenerate ids deterministically so presentation updates do not change source identity.

Changes

labkit.ui 3.2.0 -> 3.2.3
Batch Crop, Curvature, Image Enhance, and Image Match patch bumped where layouts or image-app behavior changed.

Hardened file-panel entry normalization and deterministic ID regeneration.
Fixed output-size reporting and White ROI responsiveness.
Added semantic toolPanel hosts.

User and data impact

White ROI controls responded to the selected image, Batch Crop reported output dimensions consistently, and reusable tools occupied a stable named layout area. Existing source and result formats were unchanged.

Compatibility and migration

Existing file entries and image results remained readable. Deterministic ids were regenerated in memory, and the new layout host did not alter saved data.

Validation

The listed commits updated file-panel, tool-host, and focused image-app tests. Exact historical commands were not recorded.

Evidence

Main commits f2189aef, 77084fbe, and 871739cd.

Known limitations and follow-up

The first toolPanel API was later replaced by the current semantic layout and managed-interaction model.
