* feat(api): expose structured gateway errors across SDKs
Refs #3051. Add standard validation, conflict, and retry details; preserve raw transport status in Rust, Go, TypeScript, and Python; document status and recovery guidance.
This is the structured-error foundation only. Mutation result shapes, allow_missing, durable request deduplication, and exec retry semantics remain follow-up work.

* fix(python): preserve wrapped RPC cleanup handling
Inspect the original gRPC call when handling missing sandboxes during deletion waits and managed cleanup. Add intercepted cleanup regressions and clarify the error-wrapper migration contract.
Addresses the cleanup review on #3313; part of #3051.
