refactor: restructure LSP configuration and modernize plugins

- Split LSP server configs into separate files in lsp/ directory
- Replace deprecated vim.loop with vim.uv API
- Update copilot plugin (copilot.vim → copilot.lua)
- Add snacks.nvim plugin for utilities
- Simplify LSP setup using new Neovim 0.11+ APIs
- Remove hardcoded paths in favor of vim.fs.joinpath
- Clean up configuration and remove duplicate keybindings
- Remove comment.lua plugin

-        --
-        -- LSP is an initialism you've probably heard, but might not understand what it is.
-        --
-        -- LSP stands for Language Server Protocol. It's a protocol that helps editors
-        -- and language tooling communicate in a standardized fashion.
-        --
-        -- In general, you have a "server" which is some tool built to understand a particular
-        -- language (such as `gopls`, `lua_ls`, `rust_analyzer`, etc.). These Language Servers
-        -- (sometimes called LSP servers, but that's kind of like ATM Machine) are standalone
-        -- processes that communicate with some "client" - in this case, Neovim!
-        --
-        -- LSP provides Neovim with features like:
-        --  - Go to definition
-        --  - Find references
-        --  - Autocompletion
-        --  - Symbol Search
-        --  - and more!
-        --
-        -- Thus, Language Servers are external tools that must be installed separately from
-        -- Neovim. This is where `mason` and related plugins come into play.
