[cuentaprueba244w-dotcom]

Bounty: $20 (LT)

Area: .editorconfig - project formatting

Current state: No consistent formatting rules across the polyglot codebase.

What's needed: Create .editorconfig with rules for all languages: Python(4), Rust(4), TS/JS(2), Go(tabs), Makefile(tabs), YAML/JSON/MD(2).

Acceptance criteria:

• .editorconfig at repo root with root=true
• Rules cover all language in repo
• All rules specify indent_style, indent_size, charset, end_of_line

Required validation:

• Run python3 build.py
• Include the generated diagnostic .logd artifact from diagnostic/build-XXX.logd in the PR; also include diagnostic/build-XXX.json if present
• Use .github/pull_request_template.md for your submission

I’m taking this one now and will submit a scoped PR with the required diagnostics.
