Summary

• sync the PR 9c packages/app/src/{context,types}/** and packages/desktop-electron/** lane to upstream v1.4.11
• move global and directory bootstrap work onto TanStack Query-backed session, agent, and provider loading, including a regression test for directory provider refresh after sessions are already cached
• carry the upstream app-context settings and event-stream handling changes needed by the desktop shell
• align the Electron renderer channel define and Windows app-path helper updates without touching the UI rewrite carve-out

Why

This keeps the sync/desktop-app slice in lockstep with upstream as part of PR 9c under #27, while keeping the boundary tight to app context and desktop shell infrastructure. The goal is to reduce foundation drift without widening into packages/app/src/{components,pages,styles,theme,i18n}.
