Work App: a dedicated browser for work tools

A Tauri 2 shell with one child webview per configured tool. Nav on the left
with groups and a collapsible icon rail; links between configured apps switch
tabs, everything else leaves for the real browser.

Design spec in docs/superpowers/specs/2026-09-01-work-app-design.md.
