Detailed Description of the Pull Request / Additional comments

• This PR fixes two Always On Top runtime issues around
settings and the title-bar context menu.

First, it fixes a settings propagation bug where the first settings.json change after startup could be missed, so toggling an Always On Top setting did not always take effect immediately. The shared file watcher now establishes an initial timestamp baseline and correctly triggers on the first real write.

Second, it fixes the title-bar context-menu injection path for newly opened windows. The previous implementation depended on a narrow set of accessibility menu events, so some windows would not get the “Always On Top” menu entry until the shortcut was used once. The PR broadens the accepted menu event types, listens to both menu start and popup start/end events, resolves the correct top-level target window, and updates that window’s system menu reliably.

It also adds debug logging along the settings reload and system-menu update path so future reports can be traced
end to end.
