PR Summary

Medium Risk
Enables HTTP/2 and adjusts proxy/transport wiring in the Python SDK’s core HTTP client, which can affect connection behavior and compatibility with proxies/servers. Adds new HTTP/2 dependencies, so regressions would show up as request failures or subtle networking issues.

Overview
Adds HTTP/2 support for the Python SDK by enabling http2=True on both sync and async httpx transports used for main API/sandbox calls.

Refactors ApiClient construction so proxy is only passed via httpx_args when no explicit transport is provided, avoiding double proxy configuration; new tests assert the client uses the singleton/per-loop transport and does not inject proxy mounts. Dependency updates add h2 (and related lockfile entries) and a changeset bumps @e2b/python-sdk as a minor release.
