The sheet header's back arrow, close X and actions now render through
SheetHeaderIconButton, which takes the header island chrome CompactHeader
uses: 26pt frame and 16pt glyph on pointer, 44pt and 20pt on touch, muted
colour, hover fill and tooltip. Edge buttons hang into the row padding so
their glyphs sit on the content rail; the row keeps its 64pt height and the
trailing actions shrink before the title collapses.
Migrates the diagnostic, import session, model browser, changelog, plugin
logs and sheet pane actions, and moves the tool-call and tool-call overview
sheets onto SheetHeaderView. The Usage refresh and options buttons size
their glyph from the header scope. adaptive-modal-sheet and the migrated
sheets leave the raw-pressable burn-down list.
