/**
 * ObsiGate - JSDOM tests for the AI history sidebar filter (#98).
 *
 * Covers the client-side search over the AI conversation history rendered in
 * the left sidebar "Historique IA" tab:
 *   - sessions are loaded and rendered through `loadAISessionList()`
 *   - `filterAIHistory()` narrows the list by title / preview / directory /
 *     context / mode label, case- and accent-insensitively
 *   - an empty match shows a "no match" hint instead of the empty state
 *
 * Usage: node tests/frontend/ai-sidebar.test.mjs
