Restructure eldritch.nvim to match tokyonight.nvim architecture

[Copilot]

Updates eldritch.nvim to follow the modern tokyonight.nvim architecture while preserving all existing color palettes and highlight behavior.

Changes

Modular Color System (lua/eldritch/colors/)

• Separate palette files: default.lua, darker.lua, minimal.lua
• init.lua handles computed colors (diff, terminal, borders, etc.)

Plugin Highlight Groups (lua/eldritch/groups/)

• base.lua, treesitter.lua, semantic_tokens.lua, kinds.lua for core highlights
• 30+ plugin-specific files (telescope, cmp, gitsigns, neo-tree, etc.)
• init.lua with lazy.nvim auto-detection for automatic plugin loading

Updated Core

• config.lua: Added cache, plugins, style options
• util.lua: New blend_bg, blend_fg, brighten, cache functions
• theme.lua: Simplified to use modular groups system
• types.lua: Type definitions for highlights

New Features

• Plugin auto-detection: When using lazy.nvim, only installed plugins get highlights loaded
• Caching: Optional highlight caching for performance
• Configurable plugins: Enable/disable specific plugin highlights

require("eldritch").setup({
  style = "default", -- "default", "darker", or "minimal"
  cache = true,
  plugins = {
    auto = true,      -- auto-detect with lazy.nvim
    telescope = true, -- or manually enable
  },
  on_colors = function(colors) end,
  on_highlights = function(hl, colors) end,
})

All existing color values and highlight groups preserved. Colorscheme commands unchanged: colorscheme eldritch, colorscheme eldritch-dark, colorscheme eldritch-minimal.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• esm.ubuntu.com
  • Triggering command: /usr/lib/apt/methods/https /usr/lib/apt/methods/https (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

Originally eldritch.nvim was based on tokyonight.nvim repo. tokyonight repo has since changed, I want eldritch.nvim to be updated to the same standard and everything that tokyonight has, but keep eldritch existing color scheme, color palletes etc.
