build: update uv lock to sync package versions (#1026)

# What does this PR do?
[Provide a short summary of what this PR does and why. Link to relevant
issues if applicable.]

Updated `uv.lock` to reflect the latest versions of `llama-models`,
`llama-stack`, and `llama-stack-client` (bumped to 0.1.2). This ensures
dependency consistency and avoids potential issues with outdated package
references.

Added `uv-sync` hook from `uv-pre-commit` repository to ensure
synchronization of dependencies.
