Jon Kinney 903b0504e0 macos: run as LSUIElement menubar app with NSStatusItem
Ship Lan Mouse on macOS as an accessory app (no Dock icon, no main
window on launch) with a status-bar item for show/quit. Closing the
window hides it instead of quitting so the menu bar stays the primary
surface.

- build-aux/macos-lsui-element.plist: LSUIElement=true plus
  NSInputMonitoringUsageDescription and NSAppleEventsUsageDescription
  (merged into Info.plist via cargo-bundle's osx_info_plist_exts).
- lan-mouse-gtk/src/macos_status_item.rs: NSStatusItem setup via raw
  objc_msgSend FFI. Loads a bundled 22pt PNG as a template image so
  it auto-tints for light/dark menu bars.
- scripts/makeicns.sh: emit Contents/Resources/menubar-template.png
  from the existing SVG.
- scripts/copy-macos-dylib.sh: flatten cargo-bundle's preserved
  target/ subdir under Resources so NSBundle pathForResource: finds
  the template image.
- lan-mouse-gtk/src/lib.rs: register the new modules, set up a
  Cmd+Q-wired quit action, configure bundle env vars (schemas,
  XDG_DATA_DIRS, GTK_DATA_PREFIX) when running from inside the .app,
  and filter the known upstream Gtk theme-parser warning spam.

$0: Copy all Homebrew libraries into the macOS app bundle.
USAGE: $0 [-h] [-b homebrew_path] [exec_path]
OPTIONS:
-h, --help Show this help message and exit
-b Path to Homebrew installation (default: $homebrew_path)
exec_path Path to the main executable in the app bundle
(default: get from `brew --prefix`)
When macOS apps are linked to dynamic libraries (.dylib files),
the fully qualified path to the library is embedded in the binary.
If the libraries come from Homebrew, that means that Homebrew must be present
and the libraries must be installed in the same location on the user's machine.
This script copies all of the Homebrew libraries that an executable links to into the app bundle
and tells all the binaries in the bundle to look for them there.
