Implements the `lifecycle` prop on `Sandbox.create`, taking over and
deprecating the `beta_pause` functionality.
Currently supports:
- `on_timeout`: `kill` (default) | `pause`. Controls what should happen
to the sandbox when it hits end of life. Pause allows for resuming
- `auto_resume`: False (default) | True. Whether the sandbox should
autoresume on traffic
Intended for additional functionality as we update the backend to
support additional props. Blocked from deploying until the API and
client-proxy are deployed but for pre-approval.
(Meant to be extended later as add more capabilities to the API)
<!-- CURSOR_SUMMARY -->
---
> [!NOTE]
> **Medium Risk**
> Changes the API contract and request payload shape for sandbox
auto-resume and alters lifecycle/timeout behavior mapping, which could
break older integrations if backend/client versions are mismatched.
>
> **Overview**
> Adds a new `lifecycle` configuration on `Sandbox.create` (JS + Python)
to control what happens at timeout (`kill` vs `pause`) and whether
paused sandboxes auto-resume on traffic (`auto_resume`).
>
> Deprecates `betaPause`/`beta_pause` and the JS `autoPause` create
option in favor of the new lifecycle semantics, updates connect/pause
call paths accordingly, and expands tests to cover resume-on-connect and
auto-resume behaviors.
>
> Updates the OpenAPI contract and generated clients so `autoResume` is
now an object with an `enabled: boolean` flag (removing the previous
policy enum), and bumps SDK versions via a changeset.
