Commit Message

Add Standalone Activities to Temporal Nexus Operation Handler (#2918)

* Enable Nexus activity operations without regressing workflow updates

Compose standalone activity support with the workflow-update Nexus model already present on master. Shared token, callback, link, client, and cancellation paths retain both operation families.

Constraint: Preserve the workflow-update token and API contracts from master
Rejected: Choose one conflict side | each side would drop a supported Nexus operation family
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep activity execution at token type 2 and workflow update at token type 3
Tested: Focused temporal-sdk token, link, invoker, client, async activity, and cancellation tests
Not-tested: Full repository suite and real-server-only standalone activity cases

* Make sure we test attaching

* Make sure to handle ActivityAlreadyStartedException

* Add test with SANO

* Bump test server
