recon_gen.cli.dashboards

recon-gen dashboards — self-hosted HTMX/d3 dashboard server.

Replaces the X.2-era serve app2 apply (deleted X.4.a.5; clean cut, no deprecation alias since the operator was the only one who ever saw the old verb). Same shape, same options, same default behavior — read the configured DB, mount the four real apps, optionally embed the mkdocs handbook at /docs.

Severability contract (SPEC_studio.md): dashboards runs cleanly without Studio. It calls run_html_server(... studio_routes_factory= None) so no L2 cache is built, no Studio routes are mounted, and the GET / → /dashboards redirect stays in place. cli.studio is the bigger surface that adds the Studio mount on top.
