Cooperative reusable plugin examples

These examples keep customer data local to one call and register cleanup with the SDK. They do not approve themselves for cross-customer execution; the operator selects WorkerReusePolicy.ApprovedSessions after reviewing the entire deployment and its dependencies.

C#: registered byte-buffer clearing and owned disposable stream.
Python: registered bytearray clearing and owned BytesIO.
TypeScript: registered Buffer clearing and a call-local cache.

Build C# against the 0.7.0 core package set with dotnet build examples/reuse/csharp -c Release. Install the 0.3.0 Python wheel or TypeScript tarball before running those providers. Their transform function takes { "text": "hello" } and returns the authenticated host context's tenant, transformed text and UTF-8 byte count. All three speak the regular SDK protocol and can run in a trusted local profile or a matching Docker image.

Clearing one mutable buffer does not erase strings, copies, serialized output, JIT/runtime memory or library caches. Do not store sensitive data outside the session. See author best practices for files, background work, streams and review criteria.
