Refactor development scripts, CI workflows, and configurations to enhance maintainability and adherence to project standards. - Replace `bin/doc` and `bin/test` with modular restructuring: `bin/test/_default` and `bin/test/coverage`. - Introduce `.editorconfig` and `.yamllint.yml` for consistent formatting. - Add YAML, TOML, and shell linting with new scripts under `bin/lint`. - Update `.github/workflows` to align with new linting and testing workflows. - Enhance `mise.toml` with new dependencies and tools. - Refactor `.gitignore` and other setup scripts to include additional coverage and lint outputs. - Adjust documentation for consistency with new workflow changes. Ensures smoother development workflows, improved linting, and better consistency across environments.
