The chat's settings at the top right of its header; the composer keeps the message

Model, effort, subagents and an agent chat's mode were chips inside the composer, cut off or out
of reach with a long model name or every chip on. They are in the chat's header now, beside the
Terminal, the activity panel, a Tools and skills button and the menu; a new agent chat's computer
and folder sit beside the title (where an open one says where it works), and its Terminal is the
header's button as an open chat's is. The composer keeps text, attach, Dictate, Draw a picture
and Send/Stop. Where the header has no room -- measured by fitHead on every drawing and resize:
the settings cut at their end, or the place squeezed under 10rem -- they fold behind Chat
settings, which opens them as a wrapped row under the header. The new chat page shows its header.

Tests (tests/ui CI2): the composer holds only the message's controls; at 1920/1280/1024/800/390
px, for a chat and an agent chat with long model names and every chip, every button is inside the
window and not clipped by its container, nothing is drawn over another, folded or not, and the
model's menu opens; a new agent chat at 1280 and 390. Earlier tests follow the chips' new places.

 ### Changed
 
+- **The chat's settings moved to the top right of its header; the composer keeps the message.**
+  The model picker, how hard it thinks, the subagents and an agent chat's mode sat as chips inside
+  the composer, where with a long model name or every chip on they were cut off and some could not
+  be reached. They are now in the chat's header, beside the Terminal, the activity panel, the
+  chat's tools and skills (a button of its own now, still in the chat's menu too) and the menu; a
+  new agent chat's computer and folder sit beside the title, where an open one says where it
+  works. The composer holds only the message's own: the text, attach, Dictate, Draw a picture and
+  Send/Stop. Where the header has no room for the settings -- measured, so a long model name
+  counts -- they fold behind Chat settings, which opens them as a wrapped row under the header:
+  nothing is cut off or drawn over another at any width (checked at 1920, 1280, 1024, 800 and

 - **Files, in the web explorer's shape, using the window's width.** Both tabs (This computer and
   Server) are now where you are (crumbs, each part a way back), the folder tree, the list in
