## Why
Python callers need control over response history loading and a way to override the service tier for one turn. These options also need runtime compatibility checks to prevent older CLIs from silently ignoring them.
## What changed
- Add `include_turns` to sync and async thread resume/fork methods. Omission preserves server defaults; `False` skips response history loading without changing model context.
- Add `turn_service_tier` and `source` to sync and async `run()` and `turn()`, and generate both methods together to keep their options aligned.
- Require CLI `0.151.0` or newer when sending the new options, with lazy schema checks for unversioned local builds.
- Pin the bundled runtime dependency to `0.153.4` and reject unsupported runtime versions during SDK packaging.
## Testing
Add coverage for option forwarding, history flag omission and inversion, runtime version checks, cached schema probing, and packaging compatibility. Extend app-server and installed SDK smoke tests to exercise the new options.

## Why
Python SDK CI needs to exercise the checkout's CLI while retaining coverage of the wheel installation and its default runtime.
## What changed
- Run the Python SDK test suite against the same Bazel-built CLI as the TypeScript SDK tests. Build and stage `codex-code-mode-host` alongside the CLI so it can be discovered.
- Make the Python test harness prefer `CODEX_EXEC_PATH`, then a local debug build, then the installed runtime. Exclude optional turn-cost probes from recorded model requests.
- Add a separate installation job that builds the Python SDK wheel and installs it in a fresh environment.
## Testing
The installation smoke test verifies that imports resolve to the installed SDK and that its default runtime completes a mocked turn with the expected user input and final response.
