Subject: [PATCH] chore: add quality tooling (editorconfig, prettier,
 markdownlint)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds standard quality configs matching eSolia consumer repo conventions:
- .editorconfig (2-space, UTF-8, LF)
- .prettierrc (single quotes, 100 width, no trailing commas)
- .prettierignore (excludes build outputs, lockfiles)
- .markdownlint.yml (CJK-aware, relaxed line length for docs)

Closes #10

InfoSec: no security impact — tooling configuration only
