The popover/sheet split reverses — settings fold into the Git tab, the widget stacks name over branch

The titlebar widget becomes a two-line identity block: the board glyph at
22pt spanning both lines, the title over the branch (git-mode only, smaller
and secondary), the em-dash retired. New Branch… returns to the switch menu
behind a divider, revealing an inline name field — the pre-split shape. The
board settings sheet retires whole: add-git and commit identity render
inline in the Git tab's postures (BoardGitSetup.swift), the availability
rule collapses into BoardGitSetupSection.resolve, and Board ▸ Board
Settings… leaves the menu bar. Where 07's remote/credential setup surfaces
land is deliberately left open — filed on the Redesign board.
