Closes #60 - adds configurable retry logic to ClaudeSDKManager.execute_command() for transient CLIConnectionError failures (non-MCP). Changes: - src/utils/constants.py: 4 new retry default constants - src/config/settings.py: 4 new settings fields (claude_retry_max_attempts, claude_retry_base_delay, claude_retry_backoff_factor, claude_retry_max_delay) - src/claude/sdk_integration.py: _is_retryable_error() helper + retry loop wrapping asyncio.wait_for() in execute_command() Retry decision: - CLIConnectionError (non-MCP): retried with exponential backoff - asyncio.TimeoutError: not retried (user-configured timeout, intentional) - CLINotFoundError, ProcessError, CLIJSONDecodeError: not retried Default backoff: 1s → 3s → 9s, capped at 30s (CLAUDE_RETRY_MAX_ATTEMPTS=0 disables) Tests: 491 passed, 0 failed
