Validation: JSON Schemas + validator (the discipline, enforced)

The README claimed 'validated by JSON Schema' — now it is true.

/schemas holds a JSON Schema for each entity type (Person, Body,
Candidate, Jurisdiction): a stricter profile over OKF's permissive
base, tolerating unknown keys by design.

scripts/validate.py checks all 17,506 files with no third-party deps
(hand-rolled frontmatter parser + minimal schema engine):
  1. OKF conformance — every file has frontmatter with a non-empty type
  2. Schema conformance — required fields, property types, enums
  3. Link integrity — internal /-rooted links resolve

Non-zero exit on failure, so it is a CI gate. Verified with a negative
test: it catches bad enums and dead links. All 17,506 files pass today.

Makefile ties it together: make build / validate / check.
