Fix cache key for native modules build

[Dreamsorcerer]

Made a mistake here, so the key that was being saved in the cache was being computed on the built files and not matching the original key we are checking against.

This should ensure that cmu-nav-natives is correctly built in future and unrelated PRs stop deploying to Cachix.

Greptile Summary

This PR reuses the native-module cache key across the marker and build jobs. The main changes are:

• Adds a key output to the marker job.
• Computes the native-module cache key before the build runs.
• Reuses that computed key for cache restore and cache save.

Confidence Score: 4/5

The cache save path can behave incorrectly when the marker job fails before producing outputs.

• The normal cache-hit path uses the same computed key for restore and save.
• A failed marker job leaves the downstream save step with an empty key.
• That can prevent the marker cache from being saved and keep native modules rebuilding.
