/**
 * Process-global registry of MCP servers contributed by extensions/plugins.
 *
 * Plugins declare `mcpServers` in their manifest (or a `.mcp.json`), but MCP
 * connection happens in the hoo-core `mcp-loader` module's `setupMcpLoader` on `session_start`, which
 * reads from fixed file locations. This registry bridges the two: plugin
 * factories register their servers here during load, and `setupMcpLoader` reads
 * them when connecting. Mirrors the module-global approach of
 * `agent-manifest-paths.ts`.
 *
 * Entries are keyed by `source` so a reload can rebuild the set cleanly: call
 * {@link clearExtensionMcpServers} before (re)loading plugins, then register.
