release(chart): publish 0.1.7 (#3393)

## Why
Publish chart 0.1.7 after the feature PR merged from a fork and
therefore intentionally skipped the internal-branch auto-tag job.

## What
- Trigger the `chart-release/0.1.7` release lane
- Update the quickstart example to reference chart 0.1.7

## Risk Assessment
Low — the chart implementation is already merged and tested; this PR
creates its immutable release tag and OCI artifact.

## References
- Chart implementation: https://github.com/block/buzz/pull/3322
- `helm unittest` 0.8.2: 43/43 tests passed
- Local pre-push checks passed
