feat(telemetry): Integrate usage telemetry for expand-task, fix return types

This commit integrates AI usage telemetry for the `expand-task` command/tool and resolves issues related to incorrect return type handling and logging.

Key Changes:

1.  **Telemetry Integration for `expand-task` (Subtask 77.7):**\n    -   Applied the standard telemetry pattern to the `expandTask` core logic (`scripts/modules/task-manager/expand-task.js`) and the `expandTaskDirect` wrapper (`mcp-server/src/core/direct-functions/expand-task.js`).\n    -   AI service calls now pass `commandName` and `outputType`.\n    -   Core function returns `{ task, telemetryData }`.\n    -   Direct function correctly extracts `task` and passes `telemetryData` in the MCP response `data` field.\n    -   Telemetry summary is now displayed in the CLI output for the `expand` command.

2.  **Fix AI Service Return Type Handling (`ai-services-unified.js`):**\n    -   Corrected the `_unifiedServiceRunner` function to properly handle the return objects from provider-specific functions (`generateText`, `generateObject`).\n    -   It now correctly extracts `providerResponse.text` or `providerResponse.object` into the `mainResult` field based on `serviceType`, resolving the "text.trim is not a function" error encountered during `expand-task`.

3.  **Log Cleanup:**\n    -   Removed various redundant or excessive `console.log` statements across multiple files (as indicated by recent changes) to reduce noise and improve clarity, particularly for MCP interactions.
