MinimapView hitTest ignores isHidden, intercepts clicks when minimap is hidden

從原始碼編輯器中的 MinimapView.hitTest(_:) 及其 mouseDown(with:) override 開始。將 SourceEditorConfiguration 設定為 showMinimap: false 進行重現，然後確認在 minimap 原有 frame 中的點擊能到達下方的文字檢視區，且正常的 minimap 互動不受影響。

Description

When showMinimap is set to false in SourceEditorConfiguration, the MinimapView is hidden via isHidden = true. However, clicks on the right ~140px of the editor are still intercepted by the hidden minimap, preventing cursor placement in that area.

Root Cause

MinimapView.hitTest(_:) overrides NSView.hitTest but does not check isHidden:

override public func hitTest(_ point: NSPoint) -> NSView? {
    guard let point = superview?.convert(point, to: self) else { return nil }
    // ...
}

Combined with the empty mouseDown override:

override public func mouseDown(with event: NSEvent) { }

This means the hidden minimap silently swallows all click events in its frame area.

Steps to Reproduce

1. Create a SourceEditor with peripherals: .init(showMinimap: false)
2. Open any text file
3. Try to click on the right portion of the editor (where the minimap would normally be)
4. The cursor does not move — the click is eaten by the hidden minimap

Expected Behavior

When showMinimap: false, clicks should pass through to the underlying text view.

Suggested Fix

Add an isHidden guard at the top of hitTest:

override public func hitTest(_ point: NSPoint) -> NSView? {
    guard !isHidden else { return nil }
    guard let point = superview?.convert(point, to: self) else { return nil }
    // ...
}
