fix: browse project activity through cascading menus

Replace the production activity dialog with anchored project and conversation menus, preserving exact conversation navigation and adding keyboard and narrow-window coverage. Include the interactive demo and design documentation. The demo hides idle activity and removes conversation arrows; production still retains those two elements. Validation: typecheck, lint and 11 ProjectActivity tests passed. The full suite timed out after 240 seconds with an agent-package offline inventory test failure.
