NPM stays the source of truth for which domains exist; this adds an
optional enrichment layer on top of the existing NPM_INCLUDE_PATTERNS
filtering, gated behind ADMIN_PASSWORD (disabled entirely if unset).
- Force-show/force-hide any NPM-discovered host regardless of what
the include pattern would otherwise decide
- Per-host display name and check path overrides
- Manually add targets that aren't proxied through NPM at all
- Every override falls back to the NPM-derived default when unset —
a host with no override behaves exactly as before this existed
Host overrides and manual targets live in SQLite (better-sqlite3,
WAL mode) and are re-read on every 60s check tick, so admin changes
take effect within one cycle with no restart. NPM host discovery
keeps its original 10-minute cadence — only the local override reads
happen every tick.
The core merge (NPM hosts + overrides + manual targets -> final
check list) is a pure function in targets.ts, kept separate from the
checker's I/O for testability. Verified end-to-end against a local
mock NPM server (auth, force-show/hide, rename, custom check path,
manual targets, reset-to-default all propagate correctly) and against
the actual Docker build/runtime (better-sqlite3's native addon builds
and loads correctly in the Alpine image).

Polls Nginx Proxy Manager API for proxy hosts matching configurable
domain patterns (NPM_INCLUDE_PATTERNS), HTTP-checks each every 60s,
serves results as JSON (/api/status) and a terminal-aesthetic HTML
page (/). Port 3035.
NPM connection and domain filter patterns are fully configurable via
environment variables — see README and .env.example.
