Carve src/gui/app.go into the new src/ui package:
- run.go: process lifecycle (single instance, app/window, tray, startup
timing).
- mainwindow.go: view assembly + the app.Service event listener.
Route every widget update driven by Service events through fyne.Do so the
run goroutine (executeRun) no longer mutates Fyne widgets directly. Also
wrap serveSingleInstance's Show/RequestFocus, which runs on the Accept
goroutine. (Resolves refactoring problem #4.)
fyne.Do/DoAndWait only exist in Fyne v2.6+, so upgrade fyne.io/fyne/v2
v2.5.3 -> v2.6.3. Mark the tray Quit item IsQuit so Fyne's
addMissingQuitForMenu reuses it instead of appending a second, localized
Quit now that v2.6 ships Russian translations.
go build / go vet / go test -race all clean.

Rename the application, Go module path, command package, build artifacts, resource script, and embedded icon assets from PySentry/pysentry to GoSentry/gosentry.
Move portable settings to gosentry.yaml while reading legacy pysentry.yaml during the transition, then rewrite settings under the new name.
Update Windows and Linux autostart integration to use GoSentry names while cleaning up legacy PySentry registry, desktop-entry, and systemd artifacts.
Refresh README, architecture notes, roadmap, changelog, and release examples for version 0.3.0.
Switch direct YAML usage from gopkg.in/yaml.v3 to go.yaml.in/yaml/v4, the maintained YAML org fork of the archived go-yaml repository.
Update README dependency and mirroring links so the documented source repository matches the module used by the application.
