Minga.LSP.RootDetector (Minga v0.1.0)

Detects the project root for a language server by walking up from a file path and looking for root marker files.

Delegates to Minga.Project.Detector for the actual walk-up logic. This module exists as a stable API for the LSP subsystem.

Pure functions, no process state.

iex> root = Minga.LSP.RootDetector.find_root("lib/minga/editor.ex", ["mix.exs"])

true
