* 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.

* 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.

* Align JDK cache OS identity
Use the established RUNNER_OS value directly and retain process.platform only as a non-Actions fallback.

* 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.

* 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.

* 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.

* Optimize Maven configuration warm path
Avoid eager Maven XML initialization on warm JDK runs by using deterministic serializers for new Maven settings/toolchains files, lazy-loading xmlbuilder2 for existing toolchains merges, and deferring Maven configuration modules until after Java setup.
Add targeted tests for XML escaping, lazy xmlbuilder2 loading, concurrent Maven configuration, and a manual benchmark workflow for warm-path validation.

* Address Maven optimization PR feedback
Make the toolchain XML generator consistently async, remove redundant Maven configuration await handling, and reuse the existing XML test helper.
Configure CodeQL to skip generated dist output so newly split vendored chunks do not report duplicate generated-code alerts.

* Apply rubber duck review suggestions
Document XML attribute escaping, simplify Maven configuration awaiting, and add a regression test that feeds fast-path toolchains output into the merge path.

* Delete .github/codeql/codeql-config.yml
* Update codeql-analysis.yml
* Replace xmlbuilder2 in Maven toolchain merge
Use fast-xml-parser for existing toolchains.xml parsing and serialize merged Maven toolchains deterministically. This removes the bundled xmlbuilder2 DOM/XML builder chunk from dist while preserving merge behavior for custom attributes, custom toolchains, partial entries, duplicate filtering, and escaping.

* Move Maven benchmark out of setup-java
Remove the Maven warm-path benchmark workflow and helper script from setup-java. Benchmark coverage is being moved to actions/setup-java-benchmarks so this action repository only carries the runtime optimization, tests, and generated distribution artifacts.
