[Feat:] Add non-DAP Godot run commands for projects and scenes

[Mathijs-Bakker]

Problem

The plugin currently focuses on LSP, docs, formatting, and DAP, but it does not provide a simple built-in way to launch a Godot project or scene directly from Neovim without going through DAP.

That leaves a gap for users who want a lightweight “run/play” workflow from the editor.

A related usability problem is that “run current scene” should work from the script being edited, not only from an open .tscn buffer.

Proposed Enhancement

Add native non-DAP run commands to godotdev.nvim:

• :GodotRunProject
• :GodotRunCurrentScene
• :GodotRunScene {path}
• :GodotRunScenePicker with optional Telescope integration

Expected behavior:

• :GodotRunProject launches the current Godot project
• :GodotRunCurrentScene works from:
  • a .tscn buffer
  • a .gd buffer when the script is attached to a scene
  • a .cs buffer when the script is attached to a scene
• :GodotRunScene {path} accepts res://..., project-relative, or absolute in-project scene paths
• :GodotRunScenePicker lists project scenes via Telescope when available

Why This Helps

• Matches how people actually work in Godot: usually from script buffers, not raw scene files
• Provides a fast run/play workflow without requiring DAP
• Keeps DAP available for debugging while offering a simpler path for quick execution
• Makes the plugin more complete as a Godot external-editor workflow

Scope

• Shell out to godot on PATH
• No hard Telescope dependency
• Clear fallback behavior when Telescope is unavailable
• Documentation and tests included
