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.
smoke-test-restore-gradle-home now has just two jobs: seed the cache, then
verify --offline. The build-cache, no-extracted-cache-entries-restored and
pre-existing-gradle-home jobs move to a restored
integ-test-restore-gradle-home, wired back into suite-integ-test-caching.
The seed-build job is intentionally duplicated across the two workflows.
They use distinct cache keys, since both suites run concurrently and would
otherwise write to the same entry.
pre-existing-gradle-home stays pinned to ubuntu-latest, keeping the reason
recorded: pre-creating ~/.gradle is what stops setup-gradle relocating the
Gradle User Home to D:\a\.gradle on Windows, so the job looks for a cache
entry rooted at a different path than the seed build saved.

## Why
Issue #1013 revealed that caching was **never storing content on
Windows**. Nothing caught it because the integ-tests lost their multi-OS
matrices: these workflows used to default to `'["ubuntu-latest",
"windows-latest", "macos-latest"]'`, narrowed to ubuntu-only in bcd07e66
/ d74ee73e (Aug 2024). The Windows code path has been dark ever since.
## What
Extract the two cheapest caching tests — `restore-gradle-home` and
`basic-cache-provider` — into a new `suite-smoke-test-caching` workflow,
and run that suite on both `ubuntu-latest` and `windows-latest`.
Both tests seed a cache in one job and then verify it in a dependent job
with an `--offline` build, so a cache that stores nothing fails the
verify job rather than passing silently.
- Rename `integ-test-{restore-gradle-home,basic-cache-provider}` →
`smoke-test-*` and drop them from `suite-integ-test-caching`
- Add the new suite to both `CI-integ-test` and `CI-integ-test-full`,
each with its own concurrency group matching the sibling suites
- Include `smoke-tests` in the `integ-test-success` aggregate gate
- Ignore the generated `task-configured.txt` marker in
`workflow-samples`
- Drop a dead `needs.determine-suite` guard on the `build-distribution`
step — `CI-integ-test` has no such job, so it always evaluated to true
The suite runs on Windows in PR CI (not just `CI-integ-test-full`)
specifically so the failure is visible on this PR and the fix can be
verified the same way.
## Expected result
This PR is expected to be **red on Windows**.
`restore-gradle-home-dependencies-cache` and `basic-cache-verify-build`
should fail with dependency-resolution errors under `--offline` — that
is the bug from #1013 being caught. The ubuntu legs should stay green.
Cross-OS cache keys are safe: both providers include `RUNNER_OS` in the
key (`sources/src/cache-service-basic.ts:146`), so the matrix legs don't
collide.

## Summary
- **New `basic` cache provider**: Adds an open-source (MIT-licensed)
caching implementation built on `@actions/cache` as an alternative to
the proprietary Enhanced Caching. Users can opt in with `cache-provider:
basic` on both `setup-gradle` and `dependency-submission` actions.
- **Revamped licensing & distribution docs**: Replaces the verbose
licensing notice block (previously shown in README, docs, and logs) with
a friendlier callout and a new dedicated
[DISTRIBUTION.md](./DISTRIBUTION.md) covering component licensing, usage
tiers, data privacy ("Safe Harbor"), and opt-out instructions.
- **Improved messaging**: Enhanced Caching and Basic Caching each
display concise, informative log messages and job summary notes instead
of the previous wall-of-text license warning.
- **New integration tests**: Adds `integ-test-basic-cache-provider.yml`
workflow that seeds and verifies the basic cache provider across
platforms, plus unit tests for `BasicCacheService` and `getCacheService`
selection logic.
- **CI workflow reorganization**: Dependency-submission integration
tests extracted into their own reusable suite
(`suite-integ-test-dependency-submission.yml`); sample project tests
moved into the caching suite.

Removes support for configuration-cache extraction and restore from the
caching workflow and related source code. Configuration-cache support
only worked for a limited set of projects (gradle/actions#21), and we
plan to reimplement this properly as part of the
`gradle-actions-caching` project.
The main impact is simplification of the caching logic, focusing only on
common Gradle artifacts. The `ConfigurationCacheEntryExtractor` class
and related logic were deleted from
`sources/src/caching/gradle-home-extry-extractor.ts`.
