Wraps the `plugins::reload_plugins()` primitive provided by the foundation +//! commit. The primitive clears the in-memory registry and repopulates from +//! `~/.cc-rust/plugins/installed_plugins.json`, then emits +//! `PluginEvent::Reloaded` on the subsystem event bus. +//! +//! # Session re-wiring +//! +//! Plugin contributions (tools, skills, MCP servers) are discovered via +//! `discover_plugin_tools()`, `discover_plugin_skills()`, and +//! `discover_plugin_mcp_servers()`. Each walks the registry on every call, so +//! they pick up changes to the registry automatically -- no cache to +//! invalidate at the discovery layer. +//! +//! The long-lived session tool list (`QueryEngineState::tools`, seeded at +//! startup in `main.rs` via `registry::get_all_tools()`) is a separate +//! snapshot held by `QueryEngine`. Command handlers do not have direct +//! access to the engine (see `CommandContext` in `commands::mod`), so this +//! command cannot refresh that snapshot inline. For the current REPL this +//! matches the behaviour of `/plugin enable|disable`, which also leaves the +//! engine tool list untouched; the registry changes become visible to +//! sub-agents spawned after the reload (they call `get_all_tools()` fresh) +//! and to MCP/skill discovery, which the engine re-queries each turn. +//!
