Fix: the module 'Aardvark' has no member named 'addDefaultBugReportingGestureWithEmailBugReporter` in SPM

Fix module/class name collision for SPM builds

When building with Swift Package Manager, the Aardvark module name shadows the Aardvark class, causing Aardvark.addDefaultBugReportingGestureWithEmailBugReporter to be inaccessible.

Changes:

• Expose AardvarkSwift and AardvarkMailUISwift as standalone products in Package.swift
• Add typealias to re-export Aardvark class under SPM builds
• Use Self in extension to avoid duplication
