app.dart was 1187 LOC mixing five concerns. It now keeps ClideApp +
the WidgetsApp root (~60 LOC); the shell moved to lib/src/shell/:
- root_shell.dart — keyboard/intent routing (keymap resolution,
double-tap modifiers, menu mnemonics), the overlay stack, and the
welcome overlay
- hat_bar.dart + project_switcher.dart — the window-chrome bar and
its recents/file-actions dropdown (now in src/shell, not builtin/ —
they're app chrome, not extension-shaped contributions)
- slot_host.dart — slot mounting, focus-scope integration, the
per-slot bodies incl. the workspace split + editor drag handle;
_SlotBody's static title resolver became the shared resolveTabTitle
- layout.dart — the three-column grid, status bar, collapse toggles,
bottom icon rails
app.dart re-exports RootLayout, SlotHost, StatusbarHost, and
StatusbarCollapseToggle, so every existing import (incl. the three
app-level test files) is unchanged. Pure move + minimal publics
(RootShell, HatBar, ProjectSwitcherButton); full suite green with no
test edits.
