Refreshes the bundled fixture corpus against the upstream resolver fix
(gate place-less fallback to states/counties only) and the Phase O
extended FIPS xwalk (post-2012 incorporations, Utah metro townships,
Connecticut planning regions). After regeneration:
- Salt Lake County now resolves to 20 distinct cities/townships instead
of collapsing six into Midvale's canonical_govid.
- Zero govs with conflicting populations within (year, canonical_govid).
- 593 new fips_extended canonical_govids in the xwalk (377 cities, 214
townships, 2 counties).
- Sentinel count drops from 20-39/year to 2-3/year (the residual
reflects type-2/3 entities with GOVS legacy_id but no FIPS triplet —
a separate gap, documented in cog_pipeline).
manifest.json updated with fresh SHAs, sizes, row counts, and pipeline
commit reference.
All 283 uscogdata tests pass against the new fixture.
