Other minor redirect URL changes:
- app.urls.* is now deprecated
- redirectToSignOut now sets and preserves after_auth_return_to
- OAuth sign-in after_auth_return_to now carries callback-return context
<!-- CURSOR_SUMMARY -->
---
> [!NOTE]
> **High Risk**
> High risk because it changes OAuth authorization/token issuance,
redirect URL validation, and introduces a new cross-domain handoff
endpoint plus a DB migration linking authorization codes to refresh
tokens, which can affect login/session security and reliability.
>
> **Overview**
> Adds **hosted URL targets** for SDK `urls` resolution (new `{ type:
"hosted" }`/`{ type: "handler-component" }`/`{ type: "custom" }`
options), including env-driven hosted handler domain/template support
and fallback routing for unknown `/handler/*` paths.
>
> Implements a **cross-domain OAuth PKCE handoff**: a new
`/auth/oauth/cross-domain/authorize` endpoint issues one-time
authorization-code redirects bound to the caller’s session refresh
token; authorization codes now persist `grantedRefreshTokenId` and token
issuance reuses/validates ownership of that refresh token. Redirect
planning for `redirectTo*` (and OAuth callback handling) is refactored
into `redirect-page-urls.ts` to preserve `after_auth_return_to` and
cross-domain handoff params.
>
> Tightens redirect safety (e.g., `after_callback_redirect_url` is
validated/whitelisted), centralizes SDK env var reads via `envVars` with
lint enforcement, hardens `EventTracker` startup for partial DOM test
environments, and adds unit/E2E coverage plus a demo page for manual
cross-domain verification.

## Summary by CodeRabbit
* **New Features**
* Cross-domain OAuth PKCE handoff flow (client + server) for hosted
sign-in.
* Hosted handler URL templating with local development domain suffix
support.
* Demo UI page to exercise hosted cross-domain sign-in/out and OAuth
flows.
* Authorization codes now preserve an associated refresh-token id to
support cross-domain exchanges.
* **Bug Fixes**
* Stricter redirect-URL validation and stronger refresh-token ownership
checks.
* More robust event-tracker startup guards in partial DOM environments.
* **Tests**
* New E2E and unit tests covering cross-domain authorize, callback
validation, and handoff flows.

- Introduced a fallback mechanism for the private sign-up risk engine,
allowing for zero-score assessments when the primary engine is
unavailable.
- Updated Next.js configuration to support dynamic resolution of the
private risk engine, including aliasing for both Turbopack and Webpack.
- Added a new fallback implementation in
`private-sign-up-risk-engine-fallback.ts` to ensure consistent behavior
during builds.
- Adjusted `risk-scores.tsx` to utilize the new compiled engine,
improving error handling and logging for risk assessment failures.
This update improves the robustness of the sign-up risk scoring system
and enhances the development experience by streamlining engine
resolution.

## Summary by CodeRabbit
* **Improvements**
* Sign-up risk engine is initialized and validated at startup for more
predictable performance.
* If the risk engine is unavailable or invalid, the system immediately
returns safe zero-risk scores to avoid runtime failures.
* **Tests**
* End-to-end tests updated to match the new engine initialization and
detection behavior.

> [!NOTE]
> **High Risk**
> Touches authentication and OAuth token/authorize flows and changes how
client requests are validated, so regressions could cause widespread
login/client-access failures. Also includes a data migration that alters
effective security posture for existing projects.
>
> **Overview**
> Adds a **project-level toggle**
(`project.requirePublishableClientKey`) to control whether client
requests/OAuth flows must include a publishable client key, including a
DB migration that backfills existing projects to require it.
>
> Backend auth now treats the publishable client key as *optional when
allowed*, introducing a public sentinel (`__stack_public_client__`) and
returning a new specific error
(`PUBLISHABLE_CLIENT_KEY_REQUIRED_FOR_PROJECT`) across smart request
auth + OAuth `authorize`/`callback`/`token` endpoints.
>
> Dashboard and SDKs update key generation/display and request
construction to handle missing publishable keys, expose an advanced
toggle on the Project Keys page, and extend internal config overrides to
support a new `project` level; E2E/tests and schema fuzzing are expanded
accordingly, and CI adds a forward-compat migration check job when
back-compat fails.

* **Bug Fixes**
* Key validation behavior aligned with project config.
* **Tests**
* Expanded E2E and unit tests covering optional/required publishable-key
