v0.6.3

Features

• SLT TUI migration — Rewrote entire TUI from Ratatui to SuperLightTUI (5,912 → 1,417 lines, 76% reduction)
• TUI design overhaul — Status bar with cost estimate, context visual bar, git branch indicator; sidebar with FILES/CONTEXT sections and pipe-aligned layout
• Korean IME bypass — Custom Hangul composition engine (두벌식) that bypasses SLT's text_input to eliminate ASCII flicker during Korean typing
• Native markdown rendering — SLT 0.8.3 built-in markdown support replaces 94-line custom parser

Improvements

• BLACKPINK theme: pure black background, charcoal sidebar, pink accents
• Context bar color coding: pink (<60%), amber (60-80%), red (>80%)
• Tool calls display: capitalized names with file path extraction
• Softened color palette for better dark theme harmony
• Sidebar sections shown only when relevant (FILES, AGENTS, TEAM)
• Token breakdown in sidebar (system/history/tools)

Bug Fixes

• Splash art centering with manual padding (SLT center() breaks multi-width ASCII art)
• Korean preedit highlight with inverted colors (fg=BG, bg=ACCENT)
• Bridge event cap (64/frame) prevents UI lockup
• Cursor positioning fix for Korean mode (invisible ▎ for find_cursor_marker)
