refactor(shell): replace icon rail with status bar

[rivodotlove]

Summary

• Drop 56px activity rail. Top items (tools/search/favourites/open-tabs) were unimplemented stubs.
• Move shortcuts/info/settings to a 24px VS Code-style status bar pinned bottom-right.
• Frees horizontal space for sidebar + content panes.

Test plan

• pnpm dev — verify status bar renders bottom-right, 24px tall
• Sidebar resize still works
• No icon rail column on left edge
• Status bar buttons show tooltips (Shortcuts/Info/Settings)
• pnpm check clean

Poem

🐰 The shell grows sleeker, sidebar slides in wide,
A status bar hops to the bottom with pride,
Icons dance softly in rows,
Layout refactored—the new design glows! ✨
