Backport UV index configuration fixes from release-0.3.x that enable
resolution of RC dependencies from test.pypi while keeping PyPI as the
primary index.
Key changes:
- Fix install-llama-stack-client action to use test.pypi as EXTRA index
(not primary) to prevent UV from looking for all packages there first
- Add uv-run-with-index.sh wrapper that auto-detects release branches
and sets UV env vars for local pre-commit hooks
- Update pre-commit hooks to use the wrapper for all uv commands
- Add UV_INDEX_STRATEGY=unsafe-best-match to allow checking multiple indexes
- Pass UV env vars as Docker build args and use them inline only for
llama-stack installation to avoid affecting distribution deps
- Export UV env vars to GITHUB_ENV in setup-runner for cross-step persistence
This infrastructure allows future release branches to work correctly
without manual UV configuration.

## Test Plan
# What does this PR do?
relates to #2878
We introduce a Containerfile which is used to replaced the `llama stack
build` command (removal in a separate PR).
```
llama stack build --distro starter --image-type venv --run
```
is replaced by
```
llama stack list-deps starter | xargs -L1 uv pip install
llama stack run starter
```
- See the updated workflow files for e2e workflow.
## Test Plan
CI
```
❯ docker build . -f docker/Dockerfile --build-arg DISTRO_NAME=starter --build-arg INSTALL_MODE=editable --tag test_starter
❯ docker run -p 8321:8321 test_starter
❯ curl http://localhost:8321/v1/chat/completions \

"role": "user",
"content": "Hello!"
