Simplify the new-tab agent launch menu (#39279)

* feat(agent-launch): simplify the new-tab agent launch menu

Drop Permissions and Arguments from the launch-mode setup panel; they are
agent defaults edited in Agent settings. Put effort levels (unlabeled) and
Fast mode on one row, and make the Launch chat/terminal buttons fill the
row at a larger size with icons. Select-mode pickers (automations, new
workspace, source control, continuation) keep both controls.

* fix(agent-launch): let current Agent settings win over launch-menu speed edits

A Fast or speed-tier edit copies the current Permissions and Arguments into the
launch draft. With no Arguments editor in the launch menu, a later settings
change was silently ignored. Launch drafts now drop Arguments stamped by older
settings; the speed choice still applies. Also stop pointing hosts without a
model list at the removed Arguments editor.

* fix(agent-launch): show Fast as a button in the launch menu

Matches the mock: an outlined Fast chip with the lightning icon in place of the
"Fast mode" switch. The chat composer keeps its switch.
