v1.1.0 — TailwindCSS v3 + v4 Version Support

TailwindCSS v3 + v4 Version Support

Every tool now accepts an optional version parameter ("v3" or "v4", defaults to "v4") so users get accurate, version-specific guidance.

What's new

• Version-aware tools — All 8 tools accept version: "v3" or version: "v4" (default)
• Centralized version config — All v3/v4 differences live in a single module (src/version/)
• Accurate install guides — v3 generates tailwind.config.js + autoprefixer; v4 generates @import "tailwindcss" + @tailwindcss/postcss
• Version-aware docs — Searches hit v3.tailwindcss.com or tailwindcss.com based on version
• v4 utility renames — convert_css_to_tailwind auto-applies v4 renames (e.g. flex-shrink → shrink)
• Version-aware palettes — generate_color_palette outputs JS config for v3, CSS @theme {} for v4
• Proper MCP logging — Fixed console.log → console.error so debug output doesn't corrupt the stdio transport
