feat(refactor): Finalize AI service migration and cleanup obsolete files

This commit completes the major refactoring initiative (Task 61) to migrate all AI-interacting task management functions to the unified service layer (`ai-services-unified.js`) and standardized configuration (`config-manager.js`).

Key Changes:

1.  **Refactor `update-task-by-id` & `update-subtask-by-id`:**

    *   Replaced direct AI client logic and config fetching with calls to `generateTextService`.

    *   Preserved original prompt logic while ensuring JSON output format is requested.

    *   Implemented robust manual JSON parsing and Zod validation for text-based AI responses.

    *   Corrected logger implementation (`logFn`/`isMCP`/`report` pattern) for both CLI and MCP contexts.

    *   Ensured correct passing of `session` context to the unified service.

    *   Refactored associated direct function wrappers (`updateTaskByIdDirect`, `updateSubtaskByIdDirect`) to remove AI client initialization and call core logic appropriately.

2.  **CLI Environment Loading:**

    *   Added `dotenv.config()` to `scripts/dev.js` to ensure consistent loading of the `.env` file for CLI operations.

3.  **Obsolete Code Removal:**

    *   Deleted unused helper files:

        *   `scripts/modules/task-manager/get-subtasks-from-ai.js`

        *   `scripts/modules/task-manager/generate-subtask-prompt.js`

        *   `scripts/modules/ai-services.js`

        *   `scripts/modules/ai-client-factory.js`

        *   `mcp-server/src/core/utils/ai-client-utils.js`

    *   Removed corresponding imports/exports from `scripts/modules/task-manager.js` and `mcp-server/src/core/task-master-core.js`.

4.  **Verification:**

    *   Successfully tested `update-task` and `update-subtask` via both CLI and MCP after refactoring.

5.  **Task Management:**

    *   Marked subtasks 61.38, 61.39, 61.40, 61.41, and 61.33 as 'done'.

    *   Includes other task content/status updates as reflected in the diff.

This completes the migration of core AI features to the new architecture, enhancing maintainability and flexibility.

The installation process, including any CLI prompts or web interfaces, must serve the exact same content and user experience regardless of whether npm, pnpm, or Yarn is used. The project uses 'module' as the package type, defines binaries 'task-master' and 'task-master-mcp', and its core logic resides in 'scripts/modules/'.

All dependencies are standard npm dependencies listed in package.json, and manual modifications are being removed.

+Since the request is vague, I'll provide helpful implementation details for testing website account setup with Yarn:
+
+For thorough testing, create a test matrix covering different browsers (Chrome, Firefox, Safari) and operating systems (Windows, macOS, Linux). Document specific Yarn-related environment variables that might affect website connectivity. Use tools like Playwright or Cypress to automate the account setup flow testing, capturing screenshots at each step for documentation. Implement network throttling tests to verify behavior under poor connectivity. Create a checklist of all UI elements that should be verified during the account setup process, including form validation, error messages, and success states. If no website component exists, explicitly document this in the project README and installation guides to prevent user confusion.

+- For environments where the website component requires integration with external authentication providers (such as OAuth, SSO, or LDAP), ensure that these flows are tested specifically when Taskmaster is installed via Yarn. Validate that redirect URIs, token exchanges, and session persistence behave as expected across all supported browsers.
+
+- If the website setup involves configuring application pools or web server settings (e.g., with IIS), document any Yarn-specific considerations, such as environment variable propagation or file permission differences, that could affect the web service's availability or configuration[2].
+
+- When automating tests, include validation for accessibility compliance (e.g., using axe-core or Lighthouse) during the account setup process to ensure the UI is usable for all users.
+
+- Capture and log all HTTP requests and responses during the account setup flow to help diagnose any discrepancies between Yarn and other package managers. This can be achieved by enabling network logging in Playwright or Cypress test runs.
+
+- If the website component supports batch operations or automated uploads (such as uploading user data or configuration files), verify that these automation features function identically after installation with Yarn[3].
+
+- For documentation, provide annotated screenshots or screen recordings of the account setup process, highlighting any Yarn-specific prompts, warnings, or differences encountered.
+
+- If the website component is not required, add a badge or prominent note in the README and installation guides stating "No website or account setup required," and reference the test results confirming this.

+For clarity, this task does not involve setting up a Yarn account. Yarn itself is just a package manager that doesn't require any account creation. The task is about testing whether any website component that is part of Taskmaster (if one exists) works correctly when Taskmaster is installed using Yarn as the package manager.
+
+To be specific:
+- You don't need to create a Yarn account
+- Yarn is simply the tool used to install Taskmaster (`yarn add taskmaster` instead of `npm install taskmaster`)
+- The testing focuses on whether any web interfaces or account setup processes that are part of Taskmaster itself function correctly when the installation was done via Yarn
+- If Taskmaster includes a web dashboard or requires users to create accounts within the Taskmaster system, those features should be tested
+
+If you're uncertain whether Taskmaster includes a website component at all, the first step would be to check the project documentation or perform an initial installation to determine if any web interface exists.

+5. Test the "welcome" or "onboarding" experience that follows successful account creation
+6. Ensure helpful tooltips and contextual help are displayed at appropriate moments during setup
+7. Verify that error messages are friendly, clear, and provide actionable guidance rather than technical jargon
+8. Test the account recovery flow to ensure users have a smooth experience if they forget credentials
