- Bumps vibn-frontend submodule to the new tabbed project shell
- Adds PROJECT_PAGE_ARCHITECTURE.md documenting the section
charters, boundary rules, and phased delivery plan
Phase 1 ships only the tab shell + Product tab live data (Gitea
file tree per codebase). Infra/Hosting tabs are stubbed and the
old 15 sidebar routes are intentionally untouched during migration.
