Add conditional JDK caching (#1201)
* Add JDK caching Cache resolved JDK tool-cache entries by exact platform and release identity, with a default-on cache-jdk input and explicit opt-out. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> * Apply batched suggestions from code review Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com> * Fix JDK cache CI validation Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> * Update brace-expansion security fix Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> * Refresh brace-expansion license metadata Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> * Refine JDK cache semantics Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> * Refine JDK cache documentation Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> * Simplify JDK cache identity Use one normalized runner OS dimension, reset the internal cache key schema for the unreleased feature, and align documentation, tests, and bundles. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> * Align JDK cache OS identity Use the established RUNNER_OS value directly and retain process.platform only as a non-Actions fallback. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> * Harden JDK cache saves and document tool-cache reuse Bind each JDK cache key to the installation identity it was computed for, keep post-job saves best-effort per entry, and state the real reuse and verification guarantee in the documentation. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> * docs: restructure README caching section Rename '## Caching dependencies' to '## Caching' and add a what-gets-cached overview table covering the dependency, wrapper, and JDK caches. Lead with the common 'cache: maven' example and the dependency-cache material, and demote JDK caching into its own subsection. Also corrects the IMPORTANT callout, which implied JDK caching required an explicit opt-in; it is enabled implicitly whenever 'cache' is set. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> * docs: fix caching documentation defects - Remove pull-request framing that compared behavior to `main`; state the tool-cache and `jdkfile` behavior directly and unconditionally. - Clarify that the JDK cache is a separate cache *entry* from the dependency and wrapper caches, while its *enablement* is coupled to `cache`, so the opening paragraph agrees with the enablement matrix. - Cite the actions/setup-java-benchmarks repository instead of an open PR and a self-referential PR comment, keeping the measured figures and caveats. - Keep the `cache`/`cache-jdk` matrix only in docs/advanced-usage.md and summarize the rules in prose in README.md to avoid divergence. - Describe the guarantee that a cache key is only saved with the installation it was computed for, instead of documenting inode/size/timestamp internals.
