Remove GlobalSidebar and implement auto-enter environment flow

[Claude]

Removes the redundant GlobalSidebar navigation layer and implements Power Platform-style auto-entry into environments, eliminating the generic home page in favor of pushing users directly into their working context.

Changes

Navigation Flow

• / and /login now auto-redirect based on session state:
  • No active org → /orgs
  • Has org, no environments → /environments list
  • Has org + environments → /environments/:lastOrFirstEnvId (respects localStorage cache)
• Removed DeveloperOverview home page

Sidebar Rendering

• __root.tsx: Removed GlobalSidebar and isGlobalShellPath() helper; authenticated layout now renders only TopBar + content
• environments.$environmentId.tsx: AppSidebar now renders for all routes under /environments/:envId/* except /packages
• When no package is selected, AppSidebar receives selectedPackage: null and fetches environment-wide metadata (existing behavior from client.meta.getItems(type, packageId ? { packageId } : undefined))

Preserved

• global-sidebar.tsx kept on disk for potential future reuse
• /api-console, /orgs, and /environments list pages remain sidebar-free
• TopBar switchers (org/env/package) continue to drive context switching

Result

Route	Before	After
/	Generic home	Auto-redirect to environment
/environments/:id	GlobalSidebar	AppSidebar (env-wide metadata)
/environments/:id/:pkg	AppSidebar	AppSidebar (package-filtered)
/environments/:id/packages	GlobalSidebar	No sidebar
