Feature Request: Right-to-Left (RTL) and Arabic Complex Text Shaping Support

[DIDOUOUGHA]

Arabic and other Right-to-Left (RTL) scripts currently render disconnected (isolated glyphs)

and in reverse visual order (LTR direction).

Current Behavior:
- Arabic text stored in logical memory order is displayed left-to-right on the terminal grid.
- Letters are not joined into their contextual shapes (initial, medial, final forms).
- Fallback fonts (e.g., `Noto Sans Arabic`) render individual glyphs, but text remains

visually inverted and unshaped.

Expected Behavior:
- Support for bidirectional text layout (Unicode BiDi / UAX #9) so that RTL sequences flow

right-to-left.
- Complex text shaping (via HarfBuzz or similar text shaping engine) to properly connect
Arabic characters.
- Proper handling of mixed LTR/RTL text and cursor positioning.

Environment:
- **OS:** Linux (Ubuntu 24.04)
- **Ghostty Version:** 1.3.1
- **Configured Fonts:** `JetBrains Mono`, `Noto Sans Arabic`

Additional Context:
Terminal emulators such as WezTerm and VTE-based terminals (GNOME Terminal, Ptyxis) handle

this via FriBidi/HarfBuzz integration. Native support or an optional BiDi rendering pipeline in
Ghostty would significantly improve accessibility for Arabic and RTL language speakers.

You didn't even bother to unindent the output or replace the (Run `ghostty --version` and paste output here) an LLM spit out for you. Also this is 100% a duplicate.
