The desktop app is a browser now, so it cannot write files. This adds the other half: a loopback HTTP server that serves the web build and owns the two files the browser cannot touch -- `~/todo/BACKLOG.md`, which the user's tooling and the todo MCP server read, and a disk copy of the note log so a wiped Chrome profile is not a total-loss event for unsynced notes. Notable details: - Binds to 127.0.0.1 only. The endpoints overwrite files in the user's home with no authentication, so a routable bind would let anything on the network rewrite the backlog. - Serves explicit content types. CanvasKit refuses a `.wasm` labelled anything else and the app then renders nothing at all. - Mirroring to disk is debounced. The store persists on every keystroke, so mirroring eagerly meant an HTTP request plus a whole-log write per character; IndexedDB still gets every keystroke, only the durability copy waits. Separately, this fixes a pre-existing destructive bug found while testing: `settings_screen_test` did real file I/O and overwrote the user's canonical `~/todo/BACKLOG.md` with a single fake note on *every* `flutter test` run. It went unnoticed because the app rewrites the file whenever it launches. The export destination is now injectable and the test redirects it to a temp dir; verified that a full suite run leaves the real file byte-identical.
