Proposal: Add .editorconfig for consistent formatting

Hi fellow maintainers,

I’ve opened a pull request to add an .editorconfig file to the AWK track repository.

The main goal is to automate basic code formatting (like ensuring a final newline) to prevent common CI failures and make the contribution process smoother for everyone.

The full motivation and a detailed breakdown of the proposed configuration are in the pull request description.
