/**
 * Lifecycle/admin surface of the Indexer.
 *
 * Used by entrypoints that own the index lifetime: bin/sverklo.ts,
 * mcp-server, http-server, indexer-pool, and src/index.ts. These are
 * the only consumers that should construct, mutate, or close the
 * underlying database — everything else should hold a narrower
 * read-only or memory interface.
 *
 * Keep in sync with `class Indexer` in indexer.ts. Full plan:
 * docs/refactor-plan-indexer-coupling.md.
