Python SDK v9.15.0

Changed

• The project_slug parameter docs now mention LATITUDE_PROJECT_SLUG. That variable is read by the Latitude CLI only — it has no effect here, where the project slug is still passed on every call.
• Regenerated on Fern CLI 5.58.0 → 5.122.0 and fern-python-sdk 5.15.0 → 5.31.0. No change to the HTTP API surface or to any method signature: every endpoint keeps the arguments it had. The runtime gains SSE reconnect handling, TCP keepalive options, and alias coercion in model parsing.
• Passing a custom httpx_client without an explicit timeout now leaves the timeout to that client instead of copying its timeout.read onto each request. Behavior is unchanged when timeout is set or when the SDK builds its own client (60s).
