Subject: [PATCH] feat(mobile): rework Session and Project headers for narrow
 viewports

Session header: breadcrumb (Projects > project) wrapped in
hidden sm:flex; active file path hidden on mobile; session name cap
max-w-[140px] sm:max-w-[280px]; padding px-3 sm:px-4. Mobile gets
just hamburger | session name | model pill.

Project header: px-3 sm:px-6, py-2 sm:py-3, heading text-base
sm:text-lg, project path hidden sm:block, "New session" button is
icon-only on mobile via <span className="hidden sm:inline">. Both
headers retain the safe-area-inset-top padding from v1.6.
