style: format plugin conformance handlers

[wangyb-A]

Summary

• apply the repository's configured Spotless formatting to six plugin conformance handlers
• restore a clean project-wide spotless:check
• make no behavioral changes

spotless check was failing, e.g.: https://github.com/aws/aws-durable-execution-sdk-java/actions/runs/30674290202/job/91298216229?pr=585

Validation

• mvn -q spotless:check — passed
• mvn -q -pl conformance-tests package -DskipTests — passed
• verified the diff contains exactly the six files reported by Spotless

Codex AI review

No actionable findings. The PR only reformats Javadocs and does not change runtime behavior or public APIs. Tests were not run per review constraints; residual risk is limited to formatting validation.

This PR (style: format plugin conformance handlers) applies Spotless line-wrapping to Javadoc comments in six files under conformance-tests/src/main/java/plugin/. I inspected every hunk in .ai-review-context/pr.diff:

• PluginFaultyAndHealthy.java, PluginParallelBranchHooks.java, PluginReplayFlags.java, PluginRetryExhaustion.java, PluginWaitOperationHooks.java — comment text is only re-wrapped; wording is byte-for-byte identical apart from where line breaks fall.
• PluginSupport.java — same re-wrapping, plus one single-line /** ... */ on isStep expanded to a multi-line block. No change to the method body or the "STEP".equals(type) logic.

There are no changes to executable code, method signatures, generics, serialization, checkpoint/replay logic, plugin lifecycle, or concurrency behavior. The PR is behavior-preserving as described.

Residual test risk: None from a runtime standpoint — comment-only changes cannot alter behavior, so no new or updated tests are warranted. The only thing this diff cannot itself prove is that the wrapped output actually satisfies spotless:check; that is validated by CI's mvn spotless:check (which the PR states now passes) rather than by any test in this repo.
