feat: Notch Overflow — access menu bar icons hidden behind the camera notch

[mehmetnadir]

Summary

On Macs with a camera notch (MacBook Pro 14"/16", MacBook Air M2+), when there are many menu bar icons, some get pushed behind the notch and become completely inaccessible. This PR adds a Notch Overflow feature that lets users access those hidden icons.

How it works

• Uses NSScreen.safeAreaInsets (macOS 12+) to detect if the Mac has a notch
• Enumerates all menu bar extras from all running apps via the Accessibility API (AXUIElement)
• Compares each item's screen position against the notch boundary to classify as hidden or visible
• Presents a dropdown menu with all items — hidden ones highlighted in orange
• Clicking an item triggers AXPress on the original menu bar extra

Access methods

Method	Description
⌘⇧B	Global hotkey — shows overflow menu at cursor (works anywhere)
Right-click ‹	Right-click the expand/collapse button → "Show Notch Items"
Right-click ǀ	Right-click the separator → "Show Notch Items"

Screenshots

The overflow menu classifies items:

• 🟠 Orange = hidden behind the notch
• Normal = visible in the menu bar

Technical details

• New file: hidden/Features/NotchOverflow/NotchOverflowController.swift
• Uses HotKey framework (already a dependency) for the global shortcut
• Zero impact on non-notch Macs (NotchOverflowController.hasNotch returns false)
• Requires Accessibility permission (prompted on first use)
• 429 lines added, 15 modified across 8 files

Test plan

• Verify on a notch Mac: ⌘⇧B opens overflow menu at cursor
• Verify hidden items shown in orange, visible in normal color
• Verify clicking a menu item activates the original menu bar extra
• Verify right-click on expand button shows "Show Notch Items"
• Verify right-click on separator shows "Show Notch Items"
• Verify on a non-notch Mac: no UI changes, no overhead
• Verify Accessibility permission prompt appears on first use
