Partial revert of the extraction in #1027. The caching smoke test should
answer one question quickly — does a seeded cache let a later build run
`--offline`? Everything else is integration-level.
Replaces #1031 and #1030, squashed into a single commit.
## Layout
`smoke-test-restore-gradle-home.yml` — two jobs:
| job | purpose |
|---|---|
| `restore-gradle-home-seed-build` | seed the cache |
| `restore-gradle-home-dependencies-cache` | verify the restored cache
allows `--offline` |
`integ-test-restore-gradle-home.yml` — restored, wired back into
`suite-integ-test-caching`:
| job | purpose |
|---|---|
| `restore-gradle-home-seed-build` | seed the cache (duplicated, see
below) |
| `restore-gradle-home-build-cache` | local build-cache restored |
| `restore-gradle-home-no-extracted-cache-entries-restored` | build
works with cache entries skipped |
| `restore-gradle-home-pre-existing-gradle-home` | pre-existing GUH
overwritten by restore |
This file is identical to the pre-#1027 original except for the
`dependencies-cache` job, which the smoke test now owns. All four jobs
keep the `runner-os` matrix.
## Notes
**The seed job is duplicated, with distinct cache keys.** The smoke
suite uses `smoke-test-restore-gradle-home-*`; the integ suite keeps
`restore-gradle-home-*`. This matters: `smoke-tests` and
`caching-integ-tests` run concurrently in `ci-integ-test.yml`, so
sharing a key would have both suites racing to write the same entry.
**Distinct workflow `name:`.** The smoke workflow is `Smoke test restore
Gradle Home`, so the two don't appear identically in the Actions UI.
**One thing to be aware of for the future:**
`restore-gradle-home-pre-existing-gradle-home` cannot pass on Windows.
Pre-creating `~/.gradle` is what stops `setup-gradle` relocating the
Gradle User Home to `D:\a\.gradle`, so the job looks for a cache entry
rooted at a different path than the seed build saved and never matches
it. The caching integ suite runs ubuntu-only, so this is not a problem
today — but adding Windows to that suite would surface it.
## Verification
All workflow YAML parses, and every local `uses:` reference resolves —
no dangling paths after the rename and re-add.
