feat(task-90): Complete subtask 90.1

- Implement secure telemetry capture with filtering - Enhanced ai-services-unified.js to capture commandArgs and fullOutput in telemetry - Added filterSensitiveTelemetryData() function to prevent sensitive data exposure - Updated processMCPResponseData() to filter telemetry before sending to MCP clients - Verified CLI displayAiUsageSummary() only shows safe fields - Added comprehensive test coverage with 4 passing tests - Resolved critical security issue: API keys and sensitive data now filtered from responses
