/// Showcase the log data by sending it to the showcase server
///
/// This function processes a log file and opens a browser window to visualize
/// the thread-lock relationships recorded in the log. The visualization is
/// hosted on a web server and can help identify the patterns that led to a deadlock.
///
/// # Arguments
/// * `log_path` - Path to the log file.
///
/// # Returns
/// A Result that is Ok if the showcase succeeded, or an error if it failed.
///
/// # Errors
/// Returns an error if:
/// - Failed to read the log file
/// - Failed to process the log file
/// - Failed to open the browser
///
/// # Example
///
/// ```no_run
/// use deloxide::showcase;
/// use std::path::Path;
///
/// // After a deadlock has been detected and logged
/// let log_path = Path::new("deadlock_log.json");
/// showcase(log_path).expect("Failed to showcase deadlock visualization");
/// ```

/// Showcase the current active log file
///
/// This is a convenience function that showcases the log file that was specified
/// in the Deloxide::with_log() initialization. It's useful when you don't want to
/// keep track of the log file path manually.
///
/// # Returns
/// A Result that is Ok if the showcase succeeded, or an error if it failed.
///
/// **IMPORTANT**: This function ensures all pending log entries are flushed to disk
/// before showcasing to guarantee the log file is complete.
///
/// # Errors
/// Returns an error if:
/// - No active log file exists
/// - Failed to flush pending log entries
/// - Failed to process the log file
/// - Failed to open the browser
///
/// # Example
///
/// ```no_run
/// use deloxide::{Deloxide, showcase_this};
///
/// // Initialize with logging enabled
/// Deloxide::new()
///     .with_log("deadlock_log.json")
///     .start()
///     .expect("Failed to initialize detector");
///
/// // Later, after a deadlock has been detected
/// showcase_this().expect("Failed to showcase current log");
/// ```
