Add config/18.0/ with configuration files based on OCA standards: - .pylintrc and .pylintrc-mandatory (valid-odoo-versions=18.0) - .ruff.toml (Python linting) - .pre-commit-config.yaml with updated hooks: - whool-init (new in 18.0) - oca-gen-external-dependencies (new in 18.0) - Updated prettier 3.x and eslint 9.x - eslint.config.cjs and prettier.config.cjs (new flat config format) Also move .eslintrc.yml and .prettierrc.yml to config/16.0/ since 18.0 uses the new CJS flat config format instead of YAML.
