- Migrate all serial commands from ASCII text to binary KS/KR frame protocol
(SETLAYER, TD_LIST, COMBO_LIST, LEADER_LIST, KO_LIST, etc.)
- Add config import/export as JSON (keymaps, tap dances, combos, KO, leaders, macros)
- Merge Flash + Layout Preview into single Tools tab
- Replace WPF tree layout JSON format with flat groups+keys format:
- Top-level "keys" for absolute positioning (thumbs, isolated keys)
- "groups" with x/y/r transform, keys inside use local coordinates
- Coordinates in units (1u = 50px), w/h default 1u, r default 0
- Layout auto-refresh (5s timer) for live preview while editing externally
- Pretty-print JSON in layout preview and export
