📊 Automated CIA data refresh

Pulled the latest service.data.impl/sample-data/ CSVs from
Hack23/cia@master
(resolved to commit 9da55b5047de99fb15b654bfef3db1a8360d2180)
and re-ran the production-statistics pipeline against the same commit.

How resolution works

The workflow never introduces new files — it only refreshes CSVs
already tracked under data/cia/** and cia-data/**. Upstream paths
are resolved through a recursive basename → upstream-path index
built from the GitHub Tree API, so files living in
sub-folders (distinct_values/, framework-validation/,
risk-rule-tests/) are located correctly even though local paths
are organised differently. An <stem>_sample.csv alias is applied
for the handful of locally-renamed canonical files.

Review checklist

• CSV diffs look reasonable (no schema regressions)
• production-stats.json counts move monotonically or within reason
• Dashboards still render with the refreshed data
• No unexpected file additions or removals
