Relay 0.20.0

TL;DR: Preferences live in a settings.json you can script, the composer can guess your next message, and a new status strip replaces the usage footer.

• Preferences (theme, typography, chat width, send keys, keep awake, when threads settle) now live in a settings.json file: ~/.config/relay/ on macOS and Linux (or $XDG_CONFIG_HOME/relay/), %APPDATA%\Relay\ on Windows. Edit it from a script or an editor and every open window follows at once; a broken file shows where it broke instead of wiping your settings.
• The composer can suggest your next message after a longer turn: Tab takes it, Escape dismisses it. Off by default, turn it on in Settings → Composer.
• The usage footer is now a status strip with usage rings and compact reset times, and it says why a saved reset can't be used yet.
• The model picker offers to install a missing agent or sign in to it right there, here or on a paired computer, instead of showing a Default that can't run.
• Import from another app has "Ask an agent…": an agent reads your Codex or Claude history and proposes which projects and chats to bring over, with a list you tick.
• Antigravity gets separate Google accounts, its own questions, planning, subagents and quota readings, and compaction.
• OpenCode now steers, forks, answers side questions and runs subagents natively.
• Codex shows an estimated breakdown of what fills its context.
• Agents' multiple-choice questions show their real options, and usage limits split into each quota pool, on desktop and the phone.
• Claude connection failures show once, with a way to recover.
• The working tree refreshes with a single git status, and the app polls less while its window is in the background.
• Fixes: side questions stay in order when one is cancelled, steers OpenCode got stuck on, agents losing text written right before a tool call, shortcuts blocked by passive notices, and the Android thread jumping as rows settle.
