Enhanced Caching: Windows fixes and a cache-protocol bump

This release updates gradle-actions-caching to v1.0.0 (up from v0.7.0), which fixes two significant caching defects, both most visible on Windows:

• Cache entries failed to store at all on Windows.. Every entry failed
  with Path Validation Error: Path(s) specified in the action for caching do(es) not exist, even though the Gradle User Home was fully intact. Nothing was stored, so
  every downstream job ran against an empty Gradle User Home. The cause was a nested,
  unpatched copy of @actions/glob combined with a silently swallowed require() in
  the bundle, which left Windows path separators unnormalized.

• Cache cleanup deleted instrumented jars that were in use. A bug in key
  hashing for paths shorter than 64 characters made cleanup judge freshly created
  caches/jars-9 entries as unused and remove them, so the instrumented-jars entry
  was never saved and every job re-instrumented its classpaths.

  Also included: cache entry names are now consistent between the save and restore
  reports — restore previously fell back to showing the raw glob pattern (e.g.
  /home/runner/.gradle/caches/modules-*/files-*/*/*/*/*/) instead of dependencies.

[!IMPORTANT]
Existing cache entries are invalidated by this release. The cache protocol
version was bumped to v2, so the first run after upgrading will be a cache miss
and will repopulate the cache. No configuration changes are required.

Basic caching warns instead of failing silently

The basic (open-source) caching provider now emits a warning and reports
(Entry not saved: save failed) in the Job Summary when a cache save fails, rather
than reporting success (#​1028).

Dependency submission works with Isolated Projects

dependency-submission now disables Isolated Projects via a promoted property, so
dependency graph generation works on builds that enable it (#​1025). Thanks to @​reinsch82 for the contribution.

• Injected Develocity Gradle plugin: 4.4.2 → 4.5.0

Highlights

This release brings significant behaviour improvements to Enhanced caching, improvements to the generated Job Summary, and a number of correctness and security fixes.

1. Improved cache-cleanup mechanism. Cleanup of stale files from the Gradle User Home is now faster, and no longer depends on Gradle or a JVM. It works by inspecting the local file state directly, removing the Gradle invocation from the post-build step.
2. More granular, more stable caching. The local build cache is stored as a separate cache entry, so it can be restored and invalidated independently of the main Gradle User Home entry. Transient Gradle housekeeping files are excluded from the cache, reducing its size and improving stability.
3. Hide obsolete Job summaries in PR commments: When a new Job summary comment is added to a PR, previous outdated Job summaries are now hidden.
4. Improved caching report in the job summary. The cache report now uses a single, consistent layout across all cache states and providers. Provider information is integrated directly into the report, and per-entry details are available in an expandable section. (#​985)
5. Correctness and security fixes. A unique cache key is now used per run attempt, so re-runs no longer collide; the job summary shows the cache key string rather than an internal id; and bundled dependencies have been updated, including a ReDoS fix and a fast-xml CVE fix.

What's Changed

• Remove unnecessary dependency overrides by @​bigdaz in #​981
• Scope CI-integ-test concurrency groups per-branch by @​bigdaz in #​983

• Redesign the caching Job Summary by @​bigdaz in #​985

New: Basic Cache Provider

A new MIT-licensed Basic Caching provider is now available as an alternative to the proprietary Enhanced Caching provided by gradle-actions-caching. Choose Basic Caching by setting cache-provider: basic on setup-gradle or dependency-submission actions.

• Built on @actions/cache -- fully open source
• Caches ~/.gradle/caches and ~/.gradle/wrapper directories
• Cache key derived from build files (*.gradle*, gradle-wrapper.properties, etc.)
• Clean cache on build file changes (no restore keys, preventing stale entry accumulation)

Limitations vs Enhanced Caching: No cache cleanup, no deduplication of cached content, cached content is fixed unless build files change.

Revamped Licensing & Distribution Documentation

• New DISTRIBUTION.md documents the licensing of each component (particularly Basic Caching vs Enhanced Caching)
• Simplified licensing notices in README, docs, and runtime log output
• Clear usage tiers: Enhanced Caching is free for public repos and in Free Preview for private repos

What's Changed

• Use a unique cache entry for wrapper-validation test by @​bigdaz in #​921
• Update Dependencies by @​bigdaz in #​922
• Update dependencies and resolve npm vulnerabilities by @​bigdaz in #​933
• Add open-source 'basic' cache provider and revamp licensing documentation by @​bigdaz in #​930
• Restructure caching documentation for basic and enhanced providers by @​bigdaz in #​934
