Shader Additions:

• Added bar_spectrum.frag shader file with configurations for bar values, colors, and gradients.
• Added northern_lights.frag shader file with configurations for bar values and colors.
• Added pass_through.vert shader file for vertex data input and fragment coordinate output.

Neovim Configuration Updates:

• Updated Neovim version requirement in README.md from 0.7.2 to 0.10 and removed sections on nvim-tree, Cmp_luasnip, and Github Copilot. [1] [2] [3] [4]

Plugin Configuration Changes:

• Updated lazy-lock.json with new plugin commits and added new plugins such as blink.cmp, oil.nvim, and org-bullets.nvim.
• Updated lazy.lua to include new plugin imports and disabled change detection notifications.
• Updated alpha-nvim.lua to use XDG_CONFIG_HOME for terminal command path.
• Updated avante-nvim.lua to include new provider and behavior options, and removed some dependencies and plugins. [1] [2] [3]

Helper Function Improvements:
