---@mod codetyper Codetyper.nvim - AI-powered coding partner
---@brief [[
--- Codetyper.nvim is a Neovim plugin that acts as your coding partner.
--- It uses LLM APIs (OpenAI, Gemini, Copilot, Ollama) to help you
--- write code faster using special `.coder.*` files and inline prompt tags.
--- Features an event-driven scheduler with confidence scoring and
--- completion-aware injection timing.
