* fix(plugins): portable MCP servers get a readable name so tool names fit the 64-char cap A portable plugin's MCP server was named `<skill_namespace>__<server>`, i.e. `agent-plugin-<slug>-<sha8>__<server>`. That prefix is right for plugin-data and skill names (collision-free without coordination, and persisted on disk) but it costs ~40 chars of every `mcp__<server>__<tool>` name. Providers cap function names at 64, so the registry clamped every tool of the NVIDIA plugin to a hash-suffixed stub with the verb cut off: `mcp__agent_plugin_hermes_nvidia_72eb26b1__nvidia_app__n_3fa9c2d1`. Server names only need to be unique among loaded portable servers, and the loader already refuses a clash. `portable_mcp_server_name(key, server)` = `<plugin-slug>__<server>`, collapsed to `<plugin-slug>` when the two match (the one-server package). The loader and the desktop card's server rows both call it (the card recomputed the f-string on its own before). Skill and plugin-data namespaces are unchanged; nothing persisted refers to the server name, so no migration. Tests: the existing portable-load test now pins the relationship (server name = plugin slug + server; a long vendor tool name reaches the wire unclamped), and a new test covers the clash the digest used to hide: two enabled packages folding to one slug, second server skipped, first served. Both red on main. Docs: developer-guide/plugins/index.md. * fix(plugins): a portable MCP server is named what its mcp.json calls it, nothing prepended Drop the plugin segment too. A user's own config.yaml server named `nvidia-app` yields `mcp__nvidia_app__<tool>`; a portable plugin's server of the same name now yields the same. Duplicates are refused at load (config.yaml first, then first-loaded plugin) with a warning naming both owners. Spike, isolated HERMES_HOME, real session: a portable plugin with server `acme-tools` and tool `acme_client_get_driver_status_report` registers as `mcp__acme_tools__acme_client_get_driver_status_report`; the model found it by tool_search, called it, and reported that exact name. Same plugin on main: `mcp__agent_plugin_acme_tools_88e7456f__acme_tools__acme_153862de`.
