[feat] Code Completion on all members at the class root

[DarkGhostHunter]

Description

This is more a nitpick than a feature.

It would be great to have code completion for overridable class members from the get go, instead of writing public fun.. or pub $fo....

For example:

class UserProfile
{
    public string $name;
    
    o█
   ┌─────────────────────────────────────────────────────────────┐
   │ 🔧 $override                        Property (string)       │
   │ 🔧 $oneTimeToken                    Property (?string)      │
   │ ⚡ overture()                       Method   (void)         │
   │ ⚡ onInitialize()                   Method   (void)         │
   │ ⚡ onChange(callable $callback)    Method   (self)          │
   └─────────────────────────────────────────────────────────────┘
   │ Tab/Enter: Accept  |  ↑/↓: Navigate  |  Esc: Dismiss        │
   ───────────────────────────────────────────────────────────────
}

Dunno if the engine is capable of it.

Use case

When writing a class that extends another class, trait or interface, expecting implementing abstract methods or overridable members, without having to guess the visibility.
