fix: prevent macOS backend Dock registration

Preload a backend-only JS title accessor from an unpacked macOS resource before Next starts. Preserve Windows and Linux launch arguments, and test title semantics, process scope, argument order, and resource copying.

Based on the prevention approach proposed by marchellodev in PR #47.

+ * setter checks in with Launch Services using the main app bundle, creating
+ * an unwanted foreground application registration. Keep title writes in JS
+ * instead: the native process name stays unchanged while JS can read back
+ * its assigned title. This deliberately does not emulate native truncation
+ * or every coercion detail; assignments use String(value).
+ *
+ * Explicit launch arguments (not NODE_OPTIONS) keep the full-Electron browser
+ * helper untouched. Node-mode fork descendants can inherit this preload.
