Replace the legacy terminal flow with a shared authenticated WebSocket runtime used across web, desktop, relay, and mobile surfaces. - introduce the v3 terminal protocol with scoped attachments, snapshots, ordered output, bounded replay history, reconnects, and explicit lifecycle - harden PTY creation, restart, resize, close, force-kill, idle cleanup, shell selection, login mode, environment sanitization, and appearance sync - add runtime-aware terminal APIs with relay authentication and Electron parity - add a fullscreen mobile terminal workspace with touch scrolling, long-press selection, safe-area controls, quick keys, and Ctrl/Alt input - add terminal selection attachments, preview detection, project actions, shell settings, and localized UI - harden Ghostty rendering, resize recovery, Unicode handling, block characters, line height, and stale-row behavior - remove the obsolete terminal SSE path and update reverse-proxy guidance - expand terminal runtime, transport, input, selection, and store coverage - avoid duplicate web builds when preparing mobile assets in root CI builds
