Constraint: Windows and Linux artifacts are built on native GitHub runners from a temporary snapshot branch
Rejected: Build Windows/Linux locally on Apple Silicon | docker/wine packaging is not stable on this host
Confidence: medium
Scope-risk: moderate
Directive: This snapshot branch is transport-only and should be deleted after the release completes
Tested: local verify/build stages before snapshot creation
Not-tested: remote packaging before workflow execution
Pulls the worker process entry point, parent<->worker IPC plumbing, message validation schema, and crash-recovery handler into a single src/main/worker/entry/ module. No runtime behavior changes — only directory + file-name renames plus import-path updates: worker-entry.ts -> entry/index.ts, worker-message-handler.ts -> entry/message-handler.ts, worker-rpc.ts -> entry/rpc.ts, worker-crash-recovery.ts -> entry/crash-recovery.ts, worker-types.ts -> entry/types.ts. electron.vite.config.ts, worker-service.ts, handlers/*.ts, pi-agent-factory.ts, and worker-runner.ts updated to point at the new locations.
