Subject: Add static site builder: SQLite-backed MD→HTML pipeline
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- cmd/nebbet: CLI with build [--watch] and user add/passwd/delete/list
- internal/builder: markdown→HTML, component injection via HTML comments,
  auto importmap from lib/, fsnotify watch with 150ms debounce
- internal/db: meta.db (page index, tag queries) + search.db (FTS5)
- internal/sqlitedrv: minimal CGO database/sql driver for system libsqlite3
- internal/auth: htpasswd-compatible bcrypt password file management
- templates/base.html + admin.html, styles/main.css + admin.css
- nginx.conf with auth_basic for /admin, clean URLs, gzip
- nebbet.service systemd unit for watch daemon
- Example content/index.md and components/site-greeting.js
