> [!NOTE]
> **Medium Risk**
> Changes how instance methods merge and forward connection options (api
key/domain/headers/timeouts) to API calls in both JS and Python SDKs,
which can affect request routing and auth headers. Regression tests
reduce risk but behavior changes could impact callers relying on
previous (incorrect) defaults.
>
> **Overview**
> Fixes **missing propagation of instance `connectionConfig`** when
calling sandbox instance methods (notably `pause`/`betaPause`/`connect`,
plus related methods) so default config is always forwarded and per-call
overrides still win.
>
> In the JS SDK this centralizes option merging via a new
`resolveApiOpts()` helper and updates multiple `SandboxApi.*` calls to
use it; in the Python SDK it updates `Sandbox.connect()` and
`Sandbox.pause()` (sync + async) to pass
`self.connection_config.get_api_params(**opts)`.
>
> Adds regression tests in both SDKs to assert defaults are forwarded
and overrides are applied correctly.
