✨ Hide Interface

### Description

Provide an option to **hide the interface**, similar to how Sketch and Xcode handle UI minimization.

This would live under **View → Hide Interface** (or **Show Interface** if currently hidden), with a suggested keyboard shortcut of ⌘ ..

When **Hide Interface** is enabled:
- The **toolbar** shrinks (removing all toolbar items; the title displays the current active file).
- The **navigator area**, **inspector area**, **utility area drawer**, and **status bar** all hide.
- A **floating line/character position indicator** appears at the bottom right of the window.
- In the **View** menu:
- "Hide Interface" becomes "Show Interface"
- "Hide Navigator Area" becomes "Show Navigator Area"
- "Hide Inspector Area" becomes "Show Inspector Area"
- "Hide Utility Area" becomes "Show Utility Area"

#### Behavior Notes

- Toggling **Show/Hide Interface** and **Show/Hide Navigator/Inspector/Utility Areas** should be handled **separately**:
- If the user hides the navigator area, hides the interface, then shows the interface, the navigator area remains hidden.
- If the user hides the navigator area, hides the interface, then manually shows the navigator area, *only* the navigator becomes visible.
- When the user shows the interface again, all other interface elements will return *along with* the navigator, which remains visible.

- If any UI element is shown manually while "Hide Interface" is active, the hidden state persists for all other interface components. Re-toggling "Show Interface" restores the remaining hidden interface components.

- We should **disable animations** specifically when toggling **Hide Interface**, so the change happens **instantly**.

- Toggling **Show/Hide Interface** will only apply to the currently focused workspace

### Alternatives Considered

This approach may later serve as the default behavior for **single file mode**, where "Hide Interface" is enabled by default and a workspace can be opened from that simplified window.

### Additional Context

**Xcode** behaves similarly when opening a single file:
