Switch the repo-source Python SDK real coverage over to a pinned runtime-package flow backed by GitHub release artifacts instead of PATH or explicit binary overrides.
- add sdk/python/_runtime_setup.py to download the release codex archive for a requested CODEX_PYTHON_RUNTIME_VERSION, stage a temporary codex-cli-bin package, and install it into a target Python environment with cleanup
- refactor real integration tests to run repo-source SDK code against an isolated site-packages target that contains the staged codex-cli-bin runtime
- update examples and notebook bootstrap to install and use the runtime package, and stop consulting CODEX_PYTHON_SDK_CODEX_BIN or PATH
- switch the failing turn-run and model-selection examples to runtime-compatible model selection for the pinned release binary
- keep the main SDK runtime resolution model unchanged: explicit codex_bin or installed codex-cli-bin
Validation:
- python3 -m pytest sdk/python/tests
- RUN_REAL_CODEX_TESTS=1 CODEX_PYTHON_RUNTIME_VERSION=0.115.0-alpha.11 python3 -m pytest sdk/python/tests/test_real_app_server_integration.py
