Expose Python SDK history selection and per-turn options (#44084)

## 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.
