refactor(expand): Align expand-task with unified AI service

Refactored the `expandTask` feature (`scripts/modules/task-manager/expand-task.js`) and related components (`commands.js`, `mcp-server/src/tools/expand-task.js`, `mcp-server/src/core/direct-functions/expand-task.js`) to integrate with the unified AI service layer (`ai-services-unified.js`) and configuration management (`config-manager.js`).

The refactor involved:

- Removing direct AI client calls and configuration fetching from `expand-task.js`.

- Attempting to use `generateObjectService` for structured subtask generation. This failed due to provider-specific errors (Perplexity internal errors, Anthropic schema translation issues).

- Reverting the core AI interaction to use `generateTextService`, asking the LLM to format its response as JSON containing a "subtasks" array.

- Re-implementing manual JSON parsing and Zod validation (`parseSubtasksFromText`) to handle the text response reliably.

- Updating prompt generation functions (`generateMainSystemPrompt`, `generateMainUserPrompt`, `generateResearchUserPrompt`) to request the correct JSON object structure within the text response.

- Ensuring the `expandTaskDirect` function handles pre-checks (force flag, task status) and correctly passes the `session` context and logger wrapper to the core `expandTask` function.

- Correcting duplicate imports in `commands.js`.

- Validating the refactored feature works correctly via both CLI (`task-master expand --id <id>`) and MCP (`expand_task` tool) for main and research roles.

This aligns the task expansion feature with the new architecture while using the more robust text generation approach due to current limitations with structured output services. Closes subtask 61.37.

+# Subtasks:
+## 1. Update command parsers to recognize --simple flag [pending]
+### Dependencies: None
+### Description: Modify the command parsers for both update-task and update-subtask commands to recognize and process the new --simple flag option.
+### Details:
+Add the --simple flag option to the command parser configurations in the CLI module. This should be implemented as a boolean flag that doesn't require any additional arguments. Update both the update-task and update-subtask command definitions to include this new option.
+
+## 2. Implement conditional logic to bypass AI processing [pending]
+### Dependencies: 62.1
+### Description: Modify the update logic to check for the --simple flag and conditionally skip the AI processing pipeline when the flag is present.
+### Details:
+In the update handlers for both commands, add a condition to check if the --simple flag is set. If it is, create a path that bypasses the normal AI processing flow. This will require modifying the update functions to accept the flag parameter and branch the execution flow accordingly.
+
+## 3. Format user input with timestamp for simple updates [pending]
+### Dependencies: 62.2
+### Description: Implement functionality to format the user's direct text input with a timestamp in the same format as AI-processed updates when the --simple flag is used.
+### Details:
+Create a utility function that takes the user's raw input text and prepends a timestamp in the same format used for AI-generated updates. This function should be called when the --simple flag is active. Ensure the timestamp format is consistent with the existing format used throughout the application.
+
+## 4. Add visual indicator for manual updates [pending]
+### Dependencies: 62.3
+### Description: Make simple updates visually distinguishable from AI-processed updates by adding a 'manual update' indicator or other visual differentiation.
+### Details:
+Modify the update formatting to include a visual indicator (such as '[Manual Update]' prefix or different styling) when displaying updates that were created using the --simple flag. This will help users distinguish between AI-processed and manually entered updates.
+
+## 5. Implement storage of simple updates in history [pending]
+### Dependencies: 62.3, 62.4
+### Description: Ensure that updates made with the --simple flag are properly saved to the task or subtask's history in the same way as AI-processed updates.
+### Details:
+Modify the storage logic to save the formatted simple updates to the task or subtask history. The storage format should be consistent with AI-processed updates, but include the manual indicator. Ensure that the update is properly associated with the correct task or subtask.
+
+## 6. Update help documentation for the new flag [pending]
+### Dependencies: 62.1
+### Description: Update the help documentation for both update-task and update-subtask commands to include information about the new --simple flag.
+### Details:
+Add clear descriptions of the --simple flag to the help text for both commands. The documentation should explain that the flag allows users to add timestamped notes without AI processing, directly using the text from the prompt. Include examples of how to use the flag.
+
+## 7. Implement integration tests for the simple update feature [pending]
+### Dependencies: 62.1, 62.2, 62.3, 62.4, 62.5
+### Description: Create comprehensive integration tests to verify that the --simple flag works correctly in both commands and integrates properly with the rest of the system.
+### Details:
+Develop integration tests that verify the entire flow of using the --simple flag with both update commands. Tests should confirm that updates are correctly formatted, stored, and displayed. Include edge cases such as empty input, very long input, and special characters.

Remove direct config getter usage (from `config-manager.js`) for AI parameters; use unified service instead. Keep config getters needed for report metadata (`getProjectName`, `getDefaultSubtasks`).",
           "details": "\n\n<info added on 2025-04-24T17:45:51.956Z>\n## Additional Implementation Notes for Refactoring\n\n**General Guidance**\n\n- Ensure all AI-related logic in `analyze-task-complexity.js` is abstracted behind the `generateObjectService` interface. The function should only specify *what* to generate (schema, prompt, and parameters), not *how* the AI call is made or which model/config is used.\n- Remove any code that directly fetches AI model parameters or credentials from configuration files. All such details must be handled by the unified service layer.\n\n**1. Core Logic Function (analyze-task-complexity.js)**\n\n- Refactor the function signature to accept a `session` object and a `role` parameter, in addition to the existing arguments.\n- When preparing the service call, construct a payload object containing:\n  - The Zod schema for expected output.\n  - The prompt or input for the AI.\n  - The `role` (e.g., \"researcher\" or \"default\") based on the `useResearch` flag.\n  - The `session` context for downstream configuration and authentication.\n- Example service call:\n  ```js\n  const result = await generateObjectService({\n    schema: complexitySchema,\n    prompt: buildPrompt(task, options),\n    role,\n    session,\n  });\n  ```\n- Remove all references to direct AI client instantiation or configuration fetching.\n\n**2. CLI Command Action Handler (commands.js)**\n\n- Ensure the CLI handler for `analyze-complexity`:\n  - Accepts and parses the `--use-research` flag (or equivalent).\n  - Passes the `useResearch` flag and the current session context to the core function.\n  - Handles errors from the unified service gracefully, providing user-friendly feedback.\n\n**3. MCP Tool Definition (mcp-server/src/tools/analyze.js)**\n\n- Align the Zod schema for CLI options with the parameters expected by the core function, including `useResearch` and any new required fields.\n- Use `getMCPProjectRoot` to resolve the project path before invoking the core function.\n- Add status logging before and after the analysis, e.g., \"Analyzing task complexity...\" and \"Analysis complete.\"\n- Ensure the tool calls the core function with all required parameters, including session and resolved paths.\n\n**4. MCP Direct Function Wrapper (mcp-server/src/core/direct-functions/analyze-complexity-direct.js)**\n\n- Remove any direct AI client or config usage.\n- Implement a logger wrapper that standardizes log output for this function (e.g., `logger.info`, `logger.error`).\n- Pass the session context through to the core function to ensure all environment/config access is centralized.\n- Return a standardized response object, e.g.:\n  ```js\n  return {\n    success: true,\n    data: analysisResult,\n    message: \"Task complexity analysis completed.\",\n  };\n  ```\n\n**Testing and Validation**\n\n- After refactoring, add or update tests to ensure:\n  - The function does not break if AI service configuration changes.\n  - The correct role and session are always passed to the unified service.\n  - Errors from the unified service are handled and surfaced appropriately.\n\n**Best Practices**\n\n- Keep the core logic function pure and focused on orchestration, not implementation details.\n- Use dependency injection for session/context to facilitate testing and future extensibility.\n- Document the expected structure of the session and role parameters for maintainability.\n\nThese enhancements will ensure the refactored code is modular, maintainable, and fully decoupled from AI implementation details, aligning with modern refactoring best practices[1][3][5].\n</info added on 2025-04-24T17:45:51.956Z>",

This centralizes AI config management and supports future service changes without further refactoring.\n\n- When preparing the service call, construct the payload to include both the prompt and any schema or validation requirements expected by generateObjectService. For example, if subtasks must conform to a Zod schema, pass the schema definition or reference as part of the call.\n\n- For the CLI handler, ensure that the --research flag is mapped to the useResearch boolean and that this is explicitly passed to the core expand-task logic. Also, propagate any session or user context from CLI options to the core function for downstream auditing or personalization.\n\n- In the MCP tool definition, validate that all CLI-exposed parameters are reflected in the Zod schema, including optional ones like prompt overrides or force regeneration. This ensures strict input validation and prevents runtime errors.\n\n- In the direct function wrapper, implement a try/catch block around the core expandTask invocation. On error, log the error with context (task id, session id) and return a standardized error response object with error code and message fields.\n\n- Add unit tests or integration tests to verify that expand-task.js no longer imports or uses any direct AI client or config getter, and that all AI calls are routed through ai-services-unified.js.\n\n- Document the expected shape of the session object and any required fields for downstream service calls, so future maintainers know what context must be provided.\n</info added on 2025-04-24T17:46:51.286Z>",
