PR-05c Selected Asset Details Contract and Preview

Briefing

Implement the selected-asset details surface in the required fixed order:

1. Summary
2. Runtime Contract
3. Inputs / Preview
4. Diagnostics
5. Actions

This PR materializes the didactic core of the Assets workspace.

Objective

Deliver the first usable selected-asset details experience, including:

• summary identity/state rendering
• runtime-facing contract rendering
• inputs-by-role rendering
• first previewable input surfaces
• inline diagnostics
• action groups with routine vs sensitive separation

Dependencies

• ./PR-05a-assets-workspace-foundation-and-service-state.md
• ./PR-05b-asset-navigator-search-filters-and-selection.md

Scope

• render the fixed details skeleton
• render summary metadata and location
• render runtime contract fields such as output.format, codec, and preload
• render input groups and input selection
• implement first preview surfaces for previewable inputs
• render inline diagnostics by severity
• render action groups for:
  • Doctor
  • Build
  • Adopt
  • Register
  • sensitive operations placeholders where needed

Non-Goals

• no final staged preview/apply workflow yet
• no final lower log integration yet
• no exhaustive preview support for every asset family

Execution Method

1. Build the selected-asset details layout in the mandated section order.
2. Render summary and runtime contract from workspace state.
3. Implement inputs-by-role rendering and input selection.
4. Implement baseline preview handling for previewable types.
5. Render inline diagnostics and action grouping.

Acceptance Criteria

• selecting an asset hydrates a full details view in the fixed section order
• runtime-facing contract fields are visible without raw JSON inspection
• previewable inputs can be inspected from the details area
• diagnostics are visible inline and differentiated by severity
• routine actions and sensitive actions are visibly separated

Validation

• unit tests for selected-asset detail mapping
• unit tests for action availability by asset state
• UI smoke validation for previewable input rendering

Affected Artifacts

• AssetsWorkspace details area
• preview components
• diagnostics rendering
• action surface wiring
• tests for selected-asset detail behavior
