## What kind of change does this PR introduce?
Bug fix. Resolves DEPR-318.
## What is the current behavior?
New users who confirm their email land on `/sign-in`, then
`/organizations`, then get bounced to `/new` via a `useEffect`.
Cancelling org creation with zero orgs sends them back to
`/organizations`, which immediately redirects into `/new` again.
## What is the new behavior?
- Signup email verification redirects to `/new` directly
- `/organizations` with zero orgs shows the existing empty state instead
of force-redirecting
## To test
### One-time setup
Assuming you don’t already have a staging account with **zero** orgs:
1. On **supabase.green**, sign up with a fresh email and confirm it
2. Stop at org creation. Do **not** create an org
### On this PR
Using the [studio-staging
preview](https://studio-staging-git-dnywh-fixremove-org-redirect-supabase.vercel.app/)
from Vercel checks:
4. Sign in on the preview with that account
5. Open `/dashboard/organizations`. Expect the **Create an
organization** empty state, with no redirect to `/new`
6. Open `/dashboard/new`, click **Cancel**. Expect to land on
`/organizations` and stay there
### Compare on supabase.green
Optional. Just to show what happens currently on `master`:
7. Repeat steps 3–5 on **supabase.green**. `/organizations` should
bounce to `/new`, and **Cancel** should send you back into org creation

**Stack 3/6** of the TanStack Start migration (#46424). Stacked on
**#47110** (S2) → review that first; this PR's diff is the app shell.
> [!NOTE]
> Thin route wrappers that render the existing pages-router page
components through the compat shims (S2). Next is untouched — it builds
`pages/` and ignores `routes/`. The app doesn't function end-to-end on
TanStack until the API + project routes land (S4/S5) and the flag is
flipped.
## What's in this PR
- `routes/__root.tsx` — root layout + a `beforeLoad` that runs the
shared redirect rules; `router.tsx`.
- `routes/_auth/*` — sign-in/up, forgot/reset password, SSO/MFA/partner
sign-in, CLI login, Stripe-projects login.
- `routes/_app/*` — account (me/security/audit/tokens), `org/$slug/*`
(general/billing/team/usage/…), support.
- `routeTree.gen.ts` — **regenerated** by the tanstackStart vite plugin
for exactly the routes in this PR (the migration branch's tree
references all ~300 routes, so it can't be copied verbatim here). It's a
generated artifact; the meaningful review surface is the route files.
## Verification
On top of S1+S2: `studio` typecheck ✓, lint (0 errors) ✓.

## Summary by CodeRabbit
* **Refactor**
* Enhanced internal routing infrastructure to improve application
performance and code organization. These behind-the-scenes updates
ensure a more stable and maintainable foundation for the platform
without affecting existing functionality or user experience.
