Types and IPC contract

Domain types live under src/types/. The renderer IPC surface is defined in src/types/api/ and re-exported for deep imports via @harborclient/core/types.

When changing an IPC method in the HarborClient GUI, keep these three layers in sync (see CONTRIBUTING.md):

1. packages/core/src/types/ — domain types and Api contract
2. apps/gui/src/preload/index.ts — ipcRenderer.invoke wrappers
3. apps/gui/src/main/ipc/index.ts — ipcMain.handle handlers

Channel names follow resource:action (for example collections:list, http:send).
