v0.6.2 — TUI 80-Col Cockpit Harden + Headless Render Tests

Fixed

• TUI cockpit header no longer truncates on an 80-column terminal. The status line is now split into a left zone (spinner · wordmark · verb · agent · route) and a reserved, right-aligned HUD zone (cost · tokens · autonomy pill). Only the route truncates — with an ellipsis — when space is tight; the budget and autonomy readouts stay visible at standard width.

Added

• Headless TUI render coverage (tests/tui_render.rs) driving the real render tree through ratatui::TestBackend: boot splash, cockpit HUD, swarm lanes, diff panel, checkpoint timeline, toast, replay, and a panic-free sweep from 40 to 160 columns.
