Detailed Description

Dynamic plugin loading from shared libraries.

This file defines the plugin_loader class which handles loading collector plugins from shared libraries (.so/.dylib/.dll) at runtime.

Features:

• Cross-platform support (Linux, macOS, Windows)
• Thread-safe operations
• API version compatibility checking
• Automatic resource cleanup
• Error reporting with detailed messages

Usage:

auto loader = std::make_unique<dynamic_plugin_loader>();
 
// Load a plugin
auto plugin = loader->load_plugin("/path/to/libmy_plugin.so");
if (plugin) {
    // Use the plugin...
}
 
// Unload the plugin
loader->unload_plugin("my_plugin");
