/**
 * Plugin Registry — discovers, loads, and manages plugins.
 *
 * Core stays plugin-agnostic: it knows about the *interface*, not specific plugins.
 * Plugins are discovered from (highest priority first):
 *   1. Local dev: $FRANKLIN_PLUGINS_DIR/* (or legacy $RUNCODE_PLUGINS_DIR/*)
 *   2. User: ~/.blockrun/plugins/*
 *   3. Bundled: <franklin>/dist/plugins-bundled/* (reserved for plugins
 *      shipped inside the npm tarball — none today; social/trading/content
 *      are native subsystems, not plugins)
