Edf Controller 0.2.2

• Organize Settings into Speaker, Customized EQ, and General sections with a resizable, scrollable layout.
• Show connection status, the selected source and EQ preset, and the current volume in the menu.
• Add a volume control in Settings and a direct menu command for opening custom EQ adjustments.
• Improve EQ readability and add frequency, gain, and unavailable-state accessibility descriptions.
• Add standard Settings, Close Window, and Quit shortcuts, plus Copy and Select All for diagnostic text.
• Explain when EQ changes take effect, avoid duplicated connection errors, and disable scanning when Bluetooth is unavailable.

The minimum supported OS remains macOS 13. The signed, notarized application
includes both arm64 and x86_64 architectures.

Validation: all 42 existing tests pass. Native view rendering was inspected in
Light and Dark appearances, at minimum and expanded window sizes, and in error
and disconnected states. Physical-speaker operation, live keyboard traversal,
and VoiceOver task completion were not verified in this release session.
