fix(plugin): add missing name and allowed-tools to docs command frontmatter

Command was missing the required `name` field (needed for reliable plugin
registration and /help discoverability) and the `allowed-tools` declaration
for the MCP tools it calls (`resolve-library-id` and `query-docs`); hosts
that enforce tool allowlists would silently reject those calls at runtime.
