 * Adds a task to the agent's task list for sequential execution.
 * Each task is executed independently, and its result is passed as context to the next task.
 * Tasks are processed during the execute() method call.

 * @param {string} taskDescription - The task description/prompt to execute
 * @returns {AgentForceAgent} Returns the agent instance for method chaining
 * 
 * @example
 * const agent = new AgentForceAgent({ name: "TaskAgent", tools: ["web_fetch", "fs_write_file"] });
 * agent
 *   .task("Fetch content from a URL")
 *   .task("Extract all links from the content")
 *   .task("Save the links to a file")
