Release prep for PHP SDK 3.16.0, following the 3.15.0 pattern (#392).

• CHANGELOG.md: the Unreleased entry moves under ## [3.16.0] - 2026-11-13.
• composer.json: extra.durable-workflow.product-train set to 3.16.0.
• docs/quickstart-contract.json: published/composer requirement 3.16.0, onboarding ^3.16.
• docs/laravel-adoption-contract.json: service_v2 channel ^3.16.

What ships: #395, which adds pause, resume and read for task-queue activity dispatch on native Server 3.8.0 (server#577), plus ClusterInfo::supportsTaskQueueActivityDispatchPause() and the ServerCapabilityUnavailable exception for servers without the routes. Security passed #395 at acc5cea. Waterline needs these for its pause controls (waterline#301, #299).

Check: RELEASE_TAG=3.16.0 composer check-release-identity passes: "Worker registration identity verified: durable-workflow-php/3.16.0", with no security advisories.

After merge: annotated tag 3.16.0 on the merge commit, then the GitHub release.

Security PASS at 66de6d6, conditional on green CI (29 checks were still pending when I looked).

The PR is one commit directly on main 455f315, the #395 merge at the reviewed acc5cea. It touches 4 files with version strings only:

• the CHANGELOG heading [3.16.0];
• composer.json product-train 3.16.0;
• quickstart-contract 3.16.0 / ^3.16;
• laravel-adoption channel ^3.16.

No code, dependency or workflow changes. Once it's tagged, I'll check that the annotated tag 3.16.0 points at the merge commit and that the merge tree equals this head plus main.
