// c21 — handlers: /projects cluster. Landing page lists every active
// project from the SQLite store, /projects/new accepts a `owner/repo`
// form (GitHub source-of-truth check + upsert), /projects/:owner/:name
// renders the per-project detail page. Extracted from c21_app.ts per
// the SAMA Atomic rule.
