/**
 * Query the cached dependency graph for a specific file
 *
 * This is the main implementation for the scampi_query_graph MCP tool.
 * It performs the following steps:
 *
 * 1. Validate the directory path
 * 2. Load the cached codebase map
 * 3. Find the file in the cache
 * 4. Based on query type, return:
 *    - dependencies: Files this file imports
 *    - dependents: Files that import this file
 *    - exports: Symbols exported by this file
 *    - all: All of the above
 *
 * @param directory - Absolute path to the codebase directory
 * @param file - Relative path to the file to query
 * @param options - Query options (query type)
 * @returns Promise resolving to QueryGraphResult
 *
 * @example
 * ```typescript
 * const result = await queryGraph('/path/to/project', 'src/index.ts', {
 *   queryType: 'all'
 * });
 * console.log('Dependencies:', result.dependencies);
 * console.log('Dependents:', result.dependents);
 * console.log('Exports:', result.exports);
 * ```
 *
 * @example
 * ```typescript
 * // Query only dependencies
 * const result = await queryGraph('/path/to/project', 'src/auth/login.ts', {
 *   queryType: 'dependencies'
 * });
 * ```
