fix(ai): stop AI composer placeholder doubling to 'Ask Ask…' for the Ask agent (#1988)

The composer placeholder 'Ask {agent}…' doubles to 'Ask Ask…' for the data-query
agent whose label is 'Ask'. Route the ask agent (agentRouteName === 'ask') to its
purpose-built placeholder console.ai.askAnything ('Ask anything…', already
localized) instead. Found dogfooding the AI Ask flow.

+fix(ai): stop the AI composer placeholder doubling to "Ask Ask…" for the Ask agent
+
+The composer placeholder is `Ask {agent}…`, which reads fine for most agents
+("Ask Build…") but doubles to "Ask Ask…" for the data-query agent whose label is
+literally "Ask". The Ask agent now uses its purpose-built placeholder
+(`console.ai.askAnything` → "Ask anything…", already localized) instead. Found
+dogfooding the AI Ask flow.
