Liminal 0.0.22 — Serper search, agentcard & browser dock

v0.0.22 adds Serper-backed web search (with DuckDuckGo fallback), agentcard harness tools for operator signup flows, a Gmail compose guard on send, and an embedded browser dock on Liminal Desktop. Bootstrap skip now installs the bundled Liminal default persona without LLM generation. The full widget app stack (spawn_app / multi-window) ships disabled by default (AGENT_LIMINAL_APPS=0) while stability work continues.
