Subject: [PATCH] fix(addon): write the temporary file next to the script being
 formatted

The addon formats a temporary copy of the script instead of the file
itself, to avoid Godot's "file changed outside of Godot" pop-up. That
copy was written to the system's temporary folder, but the formatter
discovers `.editorconfig` by walking up the folders above the file it
formats. From `/tmp` it never reaches the project, so every
editorconfig-only setting was silently dropped when formatting from the
Godot editor, while the same file formatted correctly from the CLI.

Writing the temporary copy next to the original script puts it back
under the project's `.editorconfig`. The file name starts with a dot so
Godot's filesystem scanner skips it while it briefly exists.

Fixes #315

+- Fixed the Godot addon ignoring the project's `.editorconfig` when formatting. The addon formats a temporary copy of the script, and that copy now sits next to the original file so the formatter finds the project's `.editorconfig` (#315, #316)
