/**
 * Analyzes keyword density for one or more keywords in a text.
 *
 * Matching is case- and accent-insensitive, supports multi-word phrases,
 * and can optionally strip HTML before tokenization.
 *
 * Default thresholds:
 * - `minDensity`: `0.5`
 * - `maxDensity`: `3`
 *
 * @param options - Keyword density options and thresholds.
 * @returns Density metrics per keyword and analysis-level warning codes.
 *
 * @example
 * analyzeKeywordDensity({
 *   text: '<p>Project brief scope and timeline.</p>',
 *   keywords: ['project brief', 'scope'],
 *   stripHtml: true,
 * });
