0.28.0 — Agent Instruction Modes & CLI Reference

Added: 3 Base Agent Rule Modes (Verbose, Optimized, Caveman) — redesigned the Agent instructions settings into 3 distinct rule density modes. Users can choose between Verbose (full reference guide), Optimized (concise, high-density structured rules tailored for LLMs), and Caveman (ultra-compact minimal token rules).
Added: Quick CLI Commands Reference in Agent Rules — added a concise CLI cheatsheet table (kandown work, kandown list, kandown show, kandown create, kandown move, kandown assign, kandown commit) right at the top of base rules across all modes so AI agents immediately know the native CLI commands available to interact with the board.
Added: 3-Step Numbered Layout for Agent Settings — reorganized the Agent Instructions settings page into 3 clear numbered step cards: Step 1 (Base Rules mode & density), Step 2 (Project Guidelines stored in .kandown/instructions.md), and Step 3 (Live Board State data filters).
Added: Quick Preset Instruction Chips — added 1-click template insertion chips (📦 pnpm, 🧪 Test rule, 🌳 Git rule, ⚡ Task log) below the project instructions editor for adding repository rules instantly.
Added: Terminal-Style Sticky Live Preview Panel — added an independent sticky preview panel on the right with window dot indicators, token estimation badge, layer legend badges (🟢 Step 1, 🟡 Step 2, 🔵 Step 3), 1-click Copy button, and real-time interactive color highlighting when hovering over options.
