* Parses the "pretty-print" stdout format emitted by the Copilot CLI when * debug logs are written to a --log-dir directory (not captured on stdout). * This format uses ✗ for failed tool calls and ● or ✓ for successful ones. * @param {string} logContent - Raw log content as a string * @returns {

(logContent)

 * @returns {Array} Array of log entries in structured format, or empty array if not detected
