v0.8.7 — In-shell pages for tools/create/remote/help

Changed

• In-shell pages for Tools / New session / New project / Open remote / Help
  • Same full-stage pattern as Git Changes (sidebar + topbar stay; terminal replaced)
  • Shared page hero, cards, and actions layout
  • Routes: /tools, /, /project/new, /remote, /help
  • Open remote is a page with copyable editor commands (not a text drawer)
