Crawler now records the deduped cross-domain link graph (edges table).
recompute.js runs real iterative PageRank over that graph, blends it with
accumulated in-degree + the Majestic seed prior, and patches every doc's
`score` (Meili's authority tie-breaker) via partial updates — preserving
titles/bodies/embeddings and triggering no re-embedding. systemd timer runs
it every 3h so ranking sharpens as the 1.5M-page crawl densifies the graph.

Per-host politeness serialized entire same-host batches (contiguous internal
links at depth), collapsing throughput to ~1 request in flight. Randomize the
frontier claim so each batch spans many hosts.

Replace homepage-only crawling (the reason the index had ~9k docs and
useless results) with a real crawler:
- SQLite frontier (node:sqlite) — durable queue, seen-set, per-domain caps
- follows internal links to configurable depth, seeds from sitemap.xml
- robots.txt compliance + per-host politeness delay
- per-URL doc IDs (old id=domain overwrote every page of a site)
- link graph: cross-domain in-degree recorded as an authority signal
- authority score field + 'score:desc' ranking rule (relevance-first, authority tiebreak)
- body trimmed for the disk-bound VM
