✨ Add comprehensive plugin integrations and AstroNvim support

Add comprehensive plugin integrations and AstroNvim support

- Add AstroNvim integration files (astronvim-integration.lua,
  astronvim-integration-full.lua) with theme configuration,
  rainbow delimiters, and enhanced UI components
- Add init.lua plugin configuration with extensive integration
  support for aerial, alpha, cmp, dap, gitsigns, and more
- Add new plugin integrations:
  - aerial.lua: Code outline window with symbol highlighting
  - markdown.lua: Enhanced markdown syntax highlighting
  - ufo.lua: Better folding with custom fold indicators
  - window_picker.lua: Window selection styling
- Update config.lua with expanded integration options including
  aliases for native_lsp, dap, symbols_outline and support for
  blink_cmp, snacks.nvim, and colorful_winsep
- Update integrations/init.lua to load new plugin modules
- Add AstroNvim documentation (README-astronvim.md) with
  installation methods and feature overview

+# SilkCircuit for AstroNvim
+
+SilkCircuit integrates seamlessly with AstroNvim, just like any other community colorscheme.
+
+## Installation
+
+### Method 1: Simple (Recommended)
+
+Add this to your `lua/community.lua`:
+
+```lua
+return {
+  "AstroNvim/astrocommunity",
+  { import = "astrocommunity.colorscheme.catppuccin" }, -- your other colorschemes
+  { "silkcircuit/silkcircuit-nvim", name = "silkcircuit" }, -- add SilkCircuit
+}
+```
+
+Then set it as your colorscheme in `lua/plugins/astroui.lua`:
+
+```lua
+return {
+  "AstroNvim/astroui",
+  ---@type AstroUIOpts
+  opts = {
+    colorscheme = "silkcircuit",
+  },
+}
+```
+
+### Method 2: With Customization
+
+If you want to customize the theme, create `lua/plugins/silkcircuit.lua`:
+
+```lua
+return {
+  "silkcircuit/silkcircuit-nvim",
+  name = "silkcircuit",
+  opts = {
+    -- your custom options here
+    styles = {
+      comments = { italic = true },
+      keywords = { bold = true },
+      functions = { bold = true, italic = true },
+    },
+  },
+}
+```
+
+That's it! SilkCircuit will automatically integrate with all your AstroNvim plugins.
+
+## Features
+
+- Full integration with all AstroNvim plugins
+- Automatic support for telescope, neo-tree, alpha dashboard, and more
+- Rainbow delimiters with cyberpunk colors
+- Optimized for readability with vibrant cyberpunk aesthetics
+
+## Supported Integrations
+
+All standard AstroNvim integrations are supported out of the box:
+
+- aerial, alpha, cmp, dap, gitsigns, illuminate, indent-blankline
+- lualine, mason, neo-tree, notify, semantic tokens, telescope
+- treesitter, which-key, window-picker, and many more!
+
+No additional configuration needed - it just works!
