/**
 * Retrieve file contents from a codebase
 *
 * This is the main implementation for the scampi_get_files MCP tool.
 * It performs the following steps:
 *
 * 1. Validate the directory path
 * 2. Load the cache to get file summaries (if requested)
 * 3. For each requested file:
 *    - Validate the file path is within the project
 *    - Read the file content from disk
 *    - Get the cached summary if available
 *    - Handle errors gracefully (include error field if read fails)
 * 4. Return array of file contents
 *
 * @param directory - Absolute path to the codebase directory
 * @param files - Array of relative file paths to retrieve
 * @param options - Optional configuration for file retrieval
 * @returns Promise resolving to GetFilesResult
 * @throws GetFilesError if directory validation fails
 *
 * @example
 * ```typescript
 * const result = await getFiles('/path/to/project', [
 *   'src/index.ts',
 *   'src/utils.ts',
 * ]);
 * console.log(result.files.length); // 2
 * ```
 *
 * @example
 * ```typescript
 * // Without summaries
 * const result = await getFiles('/path/to/project', ['src/index.ts'], {
 *   includeSummary: false,
 * });
 * ```
