Detailed Description of the Pull Request / Additional comments

Feature Description

When using Spanish or Catalan language in Quick Accent:

• Pressing 1 + activation key (e.g., Space) now shows ¡ (inverted exclamation mark)
• Pressing / + activation key now shows ¿ (inverted question mark)

Technical Details

On US keyboard layout:

• ! is typed with Shift + 1, which registers as VK_1
• ? is typed with Shift + /, which registers as VK_SLASH_

Since Quick Accent detects virtual key codes rather than the final character, adding the inverted marks to these key mappings allows users to:

1. Type ! (Shift+1)
2. Hold the activation key (Space)
3. Select ¡ from the Quick Accent menu

Changes Made

• Languages.cs: Added VK_1 => new[] { "¡" } and VK_SLASH_ => new[] { "¿" } to Spanish (SP) language
• Languages.cs: Added same mappings to Catalan (CA) language (also uses these punctuation marks)

Backward Compatibility

The existing VK_COMMA behavior (showing ¿?¡!) is preserved for users who prefer that method.

Validation Steps Performed

• Code review verified changes follow existing patterns
• Built successfully
