Changelog

Native Scan Engine, Message Queue, /btw Side Channel

• Native scan engine: dead exports (with export * barrel resolution), clone detection (SHA-256 hash), scaffolding, stale memory — no external binary needed
• Message queue: type while x is responding, messages queue and auto-send
• /btw side channel: parallel lightweight agent for quick answers without interrupting main thread
• /resume and /reference: switch sessions or load past sessions as context
• Budget reset on session switch
• Removed all x-mcp/Rust binary dependencies

Blueprint system & modular architecture

Vertical-slice app builder (x build) with five domain blueprints (social, saas, marketplace, realtime, tooling). Natural language intent detection activates blueprints from chat. Deep context extraction parses brand docs, PRDs, and @file references into structured config. Modular internals: chat, claude, and platform split into domain modules with mock backend for deterministic testing. Chat UI: streaming markdown with line-buffered rendering, file-op indicators (+/-/~), status glyphs, and per-project awareness protocol that tracks behavioral patterns across sessions. 739 tests, 0 type errors.
