Raw JSONL to structured tree: 11,285 entity files

One record, one file. The jurisdiction tree is now real:

  us/people/                          542 federal
  us/states/<xx>/people/            7,561 state
  us/states/fl/counties/<c>/people/ 1,058 county
  .../municipalities/<m>/people/    2,124 municipal (67 FL counties)

Each file is OKF markdown + YAML frontmatter: fixed key order,
field-level source provenance, Atlas UUIDs for round-tripping,
deterministic paths and slugs. Converter passes the determinism
test: two runs, byte-identical tree.

Generated by scripts/convert_officeholders.py from
data/officeholders-v2.jsonl (unchanged).
