Add user-configurable plugin order preferences for YASR output visualization

[Copilot]

Users can now customize which output plugins are preferred for SELECT/ASK vs CONSTRUCT/DESCRIBE queries. Previously, plugin selection was determined solely by plugin priority values.

Changes

Core Plugin Selection Logic

• PersistentConfig: Added pluginOrder field storing separate arrays for select and construct query types
• getCompatiblePlugins(): Modified to respect user-defined order while maintaining priority-based fallback
• getQueryResultType(): New method detecting query type from Parser response format (json/xml/csv → select, turtle/trig → construct)

Settings UI

• Output Preferences tab: New section in TabSettingsModal with two drag-and-drop lists
• SortableJS integration: Handle-based reordering with visual feedback (ghost, chosen states)
• Immediate persistence: Changes saved to storage on drop with notification
• Theme-adaptive styling: CSS custom properties for light/dark mode compatibility

API Surface

// New YASR methods
yasr.getAvailablePlugins(): { name: string; label: string; priority: number }[]
yasr.getPluginOrder(): { select?: string[]; construct?: string[] } | undefined
yasr.setPluginOrder(order: { select?: string[]; construct?: string[] }): void

Documentation

• User guide: Step-by-step configuration instructions with use cases
• Developer guide: API reference with code examples

Example Usage

const yasr = tab.getYasr();

// Prefer raw response for SELECT queries, graph visualization for CONSTRUCT
yasr.setPluginOrder({
  select: ['response', 'table'],
  construct: ['graph', 'response']
});

UI Screenshot

The Output Preferences tab provides drag-and-drop lists for reordering plugins separately for tabular and graph query results.

Storage Format

{
  selectedPlugin: "table",
  pluginOrder: {
    select: ["table", "response", "error"],
    construct: ["graph", "response"]
  },
  pluginsConfig: { ... }
}

Backward compatible: absence of pluginOrder defaults to priority-based selection.

This section details on the original issue you should resolve

<issue_title>Allow user to set prefered yasr plugin for SELECT and CONSTRUCT queries</issue_title>
<issue_description>- [ ] The current behavior is a selection of the plugin based on the priority associated to the plugin. This should be made user configurable with the initial order being determined by the priority.

• Investigate the current behavior, does the plugin selection depend on the type of output of the query (json vs turtle)? If so, then the user will need to order 2 lists.
• Make the ordering based on an easy to use drag and drop system.
• Part of Yasgui
• Configuration in the settings window
• Persistent
• Make sure all UI elements adapt colors depending on theme
• Add tests
• Document the feature, integrate it in existing user and developer guide, don't create new files for the documentation</issue_description>
