workflow: always import passthrough modules in the host#164

Currently we use the host module if it is already imported and otherwise do a sandbox import. This can lead to importing a host module repeatedly, which is not what we want. Also add `encodings` to the passthrough list, because it leaks memory when reimported (and relies on this fix since the leak is via submodules).

vercel-headers ============== - Add request header context snapshots for running callbacks with the active Vercel header context. (#166) - Add ASGI scope and WSGI environ helpers for constructing Vercel header mappings. vercel-oidc =========== - Prepare `vercel-oidc` for independent workspace releases with dynamic dependency metadata and the shared release build hook. - Remember the freshest live request OIDC token process-wide so background SDK work can authenticate outside the originating request context. vercel-internal-telemetry ========================= - Add the standalone `vercel-internal-telemetry` package for shared internal telemetry helpers used by Vercel Python packages. vercel-queue ============ - Initial release (#158) vercel-cache ============ - Split runtime cache helpers into the standalone `vercel-cache` package. (#160) - Add strict mode support for runtime cache operations. (#161) vercel ====== - Add an experimental `vercel.unstable.sandbox` SDK with sync and async sandbox lifecycle, process, filesystem, snapshot, query, and session APIs. (#128) - Add streaming read and write support for Sandbox files and process output. (#135) - Improve Workflows sandbox execution with configurable cleanup handlers, passthrough modules, namespaced workflows, and more reliable resume/error handling. (#144, #146, #148, #153, #154, #155, #156, #162, #163, #164, #165) - Refactor internal HTTP transport handling to support streamed responses, raw bodies, timeouts, retries, and shared token resolution. (#119) vercel-celery ============= - Initial release. `vercel-celery` integration with Kombu transports for Vercel Queue auto, poll, and push delivery modes; Celery result backend backed by Vercel Runtime Cache. (#159)
