 * Determines if a tool error type should be treated as fatal.

 * Fatal errors are system-level issues that indicate the environment is in a bad state
 * and continued execution is unlikely to succeed. These include:
 * - Disk space issues (NO_SPACE_LEFT)
 *
 * Non-fatal errors are issues the LLM can potentially recover from by:
 * - Correcting invalid parameters (INVALID_TOOL_PARAMS)
 * - Trying different files (FILE_NOT_FOUND)
 * - Respecting security boundaries (PATH_NOT_IN_WORKSPACE, PERMISSION_DENIED)
 * - Using different tools or approaches
 *
 * @param errorType - The tool error type to check
 * @returns true if the error should cause the CLI to exit, false if it's recoverable
