Backport of #4001 to release-0.3.x branch.
Fixes CI failures on release branches where uv sync can't resolve RC
dependencies.
## The Problem
On release branches like `release-0.3.x`, pyproject.toml requires
`llama-stack-client>=0.3.1rc1`. RC versions only exist on test.pypi, not
PyPI. This causes multiple CI failures:
1. `uv sync` fails because it can't resolve RC versions from PyPI
2. pre-commit hooks (uv-lock, codegen) fail for the same reason
3. mypy workflow section needs uv installed
## The Solution
Configure UV to use test.pypi when on release branches:
- Set `UV_INDEX_URL=https://test.pypi.org/simple/` (primary)
- Set `UV_EXTRA_INDEX_URL=https://pypi.org/simple/` (fallback)
- Set `UV_INDEX_STRATEGY=unsafe-best-match` to check both indexes
This allows `uv sync` to resolve common packages from PyPI and RC
versions from test.pypi.
## Additional Fixes
- Export UV env vars to `GITHUB_ENV` so pre-commit hooks inherit them
- Install uv in pre-commit workflow for mypy section
- Handle missing `type_checking` dependency group on release-0.3.x
- Regenerate uv.lock with RC versions for the release branch
## Changes
- Created reusable `install-llama-stack-client` action for configuration
- Modified `setup-runner` to set UV environment variables before sync
- Modified `pre-commit` workflow to configure client and export env vars
- Updated uv.lock with RC versions from test.pypi
This is a cherry-pick of commits afa9f0882, c86e6e906, 626639bee, and
081566321 from main, plus additional fixes for release branch
compatibility.

can
0.479 conclude that llama-stack==0.3.0rc4 cannot be used.

## 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!"
