docs: set atomicWrites explicitly in the plan's ModeFile

Review of the first task caught that the commit message credited
atomicWrites while the code never set it. The property is already the
documented default in 0.3.1, so the behaviour was right, but statusctl
watches close_write,moved_to specifically because an atomic write arrives
as a rename, and leaning on a default for something the CLI depends on is
weaker than declaring it.

Both ModeFile blocks in the plan now set it, so task four does not
reintroduce the gap when it adds the second mode.

Worth recording: the review asserted atomicWrites defaults to false in
0.3.1 and concluded the shipped writes were not atomic. The v0.3.1 and
v0.3.0 documentation both read "If true (default)", so that conclusion was
wrong, though the underlying observation about the unset property was
right.

 **Goal:** A `status` singleton and drawer module owning desktop modes (`dnd`, `presentation`) as files in `$XDG_RUNTIME_DIR`, with a `statusctl` CLI so anything on the system can read, set and watch them.
 
-**Architecture:** One `pragma Singleton` in `shared/Status.qml`, symlinked into `desktop/`, holding a `FileView` per mode with `atomicWrites` and `watchChanges`. Modes are booleans; `presentation` additionally asserts an `IdleInhibitor`, pauses breaktimer through a `Process`, and drives `dnd` while recording the prior value. A thin drawer module renders a tile and a page over the singleton. `~/bin/statusctl` reads and writes the same files directly, so it works when the shell is down.

 **Tech Stack:** Quickshell 0.3.1, Qt6 QML, `Quickshell.Io.FileView`, `Quickshell.Wayland.IdleInhibitor`, bash, `inotifywait` (inotify-tools 4.23.9.0).
