 *
 *   Pull TIGER geometry/attributes into a `node:sqlite` database via the Kysely
 *   {@link DatabaseClient}.
 *
 *   Replaces the ad-hoc wget and the retired corpus TIGER build script. Pared down from isp-nexus's
 *   `generate-tiger-tiles.ts` (its per-level column mapping is the spec) into the playpen
 *   `repo-tools` idiom: an async generator of progress events, idempotent, no SpatiaLite.
 *
 *   Three levels:
 *
 *   - `tabblock20` (per state) — tabulation blocks → `tabblock20`, geometry as GeoJSON text.
 *   - `place` (per state) — incorporated/census places → `tiger_places` (attribute-only).
 *   - `addrfeat` (per county) — named street segments + ZIPs → `tiger_streets` (attribute-only).
 *
 *   `tiger_streets` + `tiger_places` match the schema the corpus `tiger` adapter reads, so this is a
 *   drop-in replacement for the retired corpus TIGER build script.
 *
 *   Flow per source unit: download (skips a valid cached zip) → unzip → stream `ogr2ogr -f
 *   GeoJSONSeq` (mapping shapefile columns to the schema, WGS84 for geometry levels) → batched
 *   inserts. Re-running a state replaces its rows.
