chore(ci): Cache prebuild entries

[Tobbe]

Windows CI has been flaky. Analyzing the logs it sees it often fails to download better-sqlite3 native binaries. It then falls back to manually building them, which always fails on Windows.

The download has been failing on Ubuntu too from time to time, but when it does and falls back to building it succeeds with the build, and CI for Ubuntu passes. But building is slow. Downloading prebuilt bins is faster.

Caching the bins when we do succeed in downloading them works around flaky downloads, and hopefully makes it even faster than actual downloads even if they had been fully stable

Greptile Summary

This PR adds caching for prebuild-install native binaries (primarily better-sqlite3) to reduce flaky Windows CI failures caused by unreliable downloads of prebuilt .node files.

• Adds a step to detect the platform-specific _prebuilds cache directory ($HOME/.npm/_prebuilds on Linux/macOS, $APPDATA/npm-cache/_prebuilds on Windows) and another step to extract the installed better-sqlite3 version from yarn.lock using a Yarn v4-compatible grep pattern.
• Inserts actions/cache/restore before yarn install (so prebuild-install can find cached binaries and skip downloading) and actions/cache/save after yarn install, with continue-on-error: true on both so failures don't break CI.

Confidence Score: 5/5

Safe to merge — the cache steps are additive, wrapped with continue-on-error, and don't touch any existing functionality.

The version extraction grep uses the correct Yarn v4 lockfile format, the cache key is version-aware preventing stale binary hits across upgrades, restore and save keys match, and both cache steps use continue-on-error so a cache miss or wrong path is a silent no-op rather than a CI failure.

No files require special attention.

.github/actions/set-up-job/action.yml	Adds prebuild-install cache restore/save steps with correct Yarn v4 grep pattern, version-aware cache key, and continue-on-error safety net; logic and ordering look sound
