Add Language Support

Adds language support to the Neovim configuration at config/nvim/.worktrees/rewrite/.

Steps

1. Create LSP config at lsp/<server-name>.lua:

Use https://github.com/neovim/nvim-lspconfig/tree/master/lsp as a starting point for the server config. Find the matching server file there and adapt it.

---@type vim.lsp.Config
return {
  cmd = { "server-binary" },
  filetypes = { "filetype" },
  root_markers = { ".git" },
  settings = {},
}

The file name must match the Mason package name. plugin/lsp.lua auto-discovers all files in lsp/.

1. Add formatter to formatters_by_ft in lua/plugins/conform.lua:

filetype = { "formatter-name" },
-- or with fallback:
filetype = { "prettierd", "prettier", stop_after_first = true },

1. Add linter to linters_by_ft in lua/plugins/lint.lua:

filetype = { "linter-name" },

1. Add filetype settings (optional) at after/ftplugin/<filetype>.lua for indent, textwidth, etc.

Mason auto-installs the LSP server, formatter, and linter on next startup.

Looking Up Names

What	Where to find
LSP servers	https://mason-registry.dev/registry/list — file name must match the Mason package name
Formatters	https://github.com/stevearc/conform.nvim — see "Formatters" section in README
Linters	https://github.com/mfussenegger/nvim-lint — see "Available Linters" section in README

Quick Reference

What	Where
LSP config	lsp/<server>.lua
Formatters	lua/plugins/conform.lua → formatters_by_ft
Linters	lua/plugins/lint.lua → linters_by_ft
Filetype opts	after/ftplugin/<ft>.lua
Mason skip list	lua/plugins/mason.lua → skip table
