chore(ci): retarget hypatia-scan wrapper to standards#193 HEAD (#48)

## Summary

The hypatia-scan wrapper in this repo was merged pinned to standards#191
HEAD `2569c10e831e293f9dd6580d82a494aca039deee`. Standards#191 was
subsequently closed in favour of standards#193 (parallel-session
implementation with a strictly simpler API — zero inputs except
`runs-on`).

The pinned commit remains git-reachable via `refs/pull/191/head` so the
workflow keeps functioning, but it doesn't track the canonical #193
implementation that's headed for main.

This PR repins the wrapper at #193 HEAD
`97df762107501909f50bb770e9bc200b6c415600` so it picks up the merged
reusable once #193 lands.

## Test plan

- [ ] After standards#193 merges, the next push uses the merged reusable
- [ ] Behaviour unchanged before then (still pinned to a reachable
commit)

Refs standards#193.
