feat(assistant): refine tool display and streaming behavior - #1390
Merged
Conversation
Add a generic tool labeler (`getToolText`/`getToolSuffix`/`getToolIcon`)
so any MCP server's tools render with clean labels, suffixes and icons
instead of falling back to raw tool names. Split the stable verb from
the dynamic detail and render it as a suffix.
Make tool output fully scrollable instead of truncating it, and parse
the standard MCP `{ content: [{ text }] }` envelope generically.
On the backend, replace the custom stop condition with `stepCountIs`,
force a final text answer on the last step via `prepareStep`, bump
`maxOutputTokens` to 8000, enable gateway caching and `smoothStream`.

Summary
Ports the relevant improvements from nuxt/nuxt.com#2265 to the Docus assistant, adapted to the generic/configurable setup (any MCP server, configurable model).
