fix(logger): address PR #19 code review feedback
Fixes: - Remove unused import logBufferMetrics from event-buffer.ts - Add safeStringify() for robust data formatting: - Handles circular references gracefully - Formats Error objects properly - Truncates large arrays [Array(n)] - Handles undefined/null/Date/BigInt values - Add getMode() method to AdaptiveTimeoutCalculator to avoid duplicating mode calculation logic in flush() - Fix empty data object handling (no trailing space) Tests: - Add comprehensive test suite (39 tests) covering: - Environment variable check (BAILEYS_LOG=false) - All logging functions with emoji verification - Session name handling - formatLogData edge cases (circular, Error, arrays, etc.)
