/**
 * Normalizes and validates raw CLI options into a standardized configuration object.
 *
 * Performs the following transformations:
 *  - Converts string/boolean flags to proper boolean values
 *  - Applies sensible defaults for optional configuration
 *  - Parses comma-separated lists (--ignore, --includeFiles, etc.)
 *  - Validates and filters category selections (--only)
 *  - Compiles regex patterns with error handling (--ignoreRegex)
 *  - Resolves file paths relative to current working directory
 *
 * @param raw - Raw options object from CLI argument parser
 * @returns Fully normalized and type-safe options object ready for use
 *
 * @example
 * const options = normalizeOptions({
 *   ci: 'true',
 *   ignore: 'TEST_,DEBUG_',
 *   only: 'unused,duplicates'
 * });
 * // Returns: { isCiMode: true, ignore: ['TEST_', 'DEBUG_'], only: ['unused', 'duplicates'], ... }
