v0.2.0 — exec, catalog, diagnostics, reboot

Adds 4 tools to the 7-tool base: get_catalog (free — plans/locations/pricing), reboot_server, server_logs (hypervisor diagnostics), and exec_command (run a command as root over SSH; needs a server provisioned with managed_key:true). provision_server gains managed_key — generate a server-side keypair and return the private key once. Account-gated tools need AGENTMETAL_API_KEY. npm: @agentmetal/mcp@0.2.0 · Registry: dev.agentmetal/agentmetal
