lohenishort/sentinel-web ? reverse-engineered prompt

Build me Sentinel Web, a self hostable website monitoring tool that crawls sites without running their JavaScript, stores the pages it finds, and flags SEO, security, and content integrity issues with evidence based reports.

I want it to work in two modes, one for enterprise use with a web API, background workers, tenant aware storage, login and roles, audit logs, and metrics, and another offline mode that runs locally from a CLI with SQLite and local file storage and no external services. Keep the analysis passive only, so it should never mutate target sites or execute downloaded code.

Please make the app able to crawl, parse, index, analyze, and generate reports in a clean pipeline, with reusable models and the same core logic in both modes. If you need to look up current docs online for any libraries or best practices, go ahead. Focus on getting the full working project in place, with sensible defaults, good error handling, and tests for the main flows.
