• [Requirement]: Support heterogeneous result types in Parallel operations aws-durable-execution-conformance-tests#74
• Depends on feat: add optional static-typing conformance suite aws-durable-execution-conformance-tests#112

Description

Adds the dedicated static_typing conformance suite with Java handlers for requirements 12-1 and 12-2:

• independently typed heterogeneous branch handles, including a parameterized Map result
• awaiting the first branch while registration remains open, then registering a second branch from that result

The suite is isolated from the general parallel suite so dynamically typed SDKs can omit it. Suite discovery automatically adds template_static_typing.yaml as a separate CI matrix job.

The conformance requirements PR should merge first so the runner installed from main recognizes the new suite.

Codex AI review

No actionable findings. Residual risk is limited to cloud-only execution of the new conformance suite, which was not run under the read-only review constraints.
