Scaffold plit-tui: ratatui + crossterm terminal UI

[theuseless-ai]

Overview

Terminal UI client for the plit ecosystem. Connects to a plit instance (local or remote via plit auth login) and provides a full interactive interface in the terminal.

Motivation

• Runs on any device with a terminal — iPhone (iSH), Raspberry Pi, SSH sessions
• Bypasses App Store on iOS
• Depends on plit auth login (plit-gw#63) for remote instance support

Architecture

• Separate crate, published to crates.io as plit-tui
• plit repo wraps it as a third [[bin]] entry (same pattern as plit-gw)
• cargo install plit gives plit + plit-gw + plit-tui
• Added to VERSION manifest as PLIT_TUI=x.y.z

Dependencies

• ratatui (TUI framework)
• crossterm (terminal backend)
• Shared: reqwest, tokio-tungstenite, serde (for gateway communication)

Blocked by

• plit-gw#63: plit auth login — needed for remote instance connection

Domain

• plit.ai acquired — future home for docs and installer

Milestone

v0.4.x
