Groups the pi Agent lifecycle, factory, signature contract, and env/redaction helpers into src/main/worker/runtime/. WorkerRunner is the module's public entry and lives in runtime/index.ts; pi-agent-factory and pi-hook-contract stay named for their role as visible runtime boundaries; helpers.ts carries ParentMessage/ChildMessage/RunJob types plus redactor + env override utilities. entry/index.ts and agent-runtime/runtime-message-injector.ts updated to import from the new paths.
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.
