split lib/app.dart into lib/src/shell/ (T-394)

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. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
