v0.18.0

• added site auto-discovery when neither a tool argument nor OMADA_SITE_ID supplies a site: single-site controllers are selected automatically; controllers with no sites or multiple sites return an explanatory error
• added createSwitchAcl and updateSwitchAcl tools with schema validation, dry-run previews, and existing-rule checks for updates
• expanded the default safe-read profile with firewall ACL and traffic read tools
• reorganized README tool tables into collapsible read and write sections
• configured repository engineering skills with GitHub Issues, default triage labels, and single-context domain documentation conventions
• updated CI and publishing actions to releases using the Node.js 24 runtime
• synchronized package and lockfile versions for the release
