Release v4.36.0

Added

• MCP can export the compiled executable model: read-workspace view executable-model returns its schema, language and semantic versions, model revision and size, plus bounded base64 pages of the exact canonical bytes. It is available only when compilation succeeded; otherwise it reports available: false and points to the executable-diagnostics view. Continuation pages must pass expectedModelRevision and expectedAttachmentManifestRevision, and are refused if the model or any attached code changed, including a code edit that changes neither the workspace nor the model revision. The exported model alone is not a proof of equivalence or a runnable attachment bundle (decision 0016).
• implementation-requirements responses include the attachment-manifest revision. Passing it back pins a continuation and refuses it if attached code changed; continuations without it work as before.
