Michael Sitarzewski 5032f7e75c feat: add agent originality check (script + CI + docs) (#560) ...

Adds scripts/check-agent-originality.sh, which flags new agents that
substantially duplicate an existing one. It compares each candidate
against the whole roster (and other files in the same change set) using
entity-neutralized 8-word shingle overlap, so a find-replace "re-skin"
that only swaps a country/platform name can't slip past review.

- CI: new "Check agent originality" step in lint-agents.yml runs it on
  changed agent files; a >=40% match fails the build.
- Docs: CONTRIBUTING.md gains a self-run "before submitting" step, a
  checklist item, and a "things we'll always close" bullet for re-skins.

Calibration: across the existing 184-agent library the worst same-pair
similarity is ~1.5% (median 0%), so the WARN >=20% / FAIL >=40% defaults
leave a wide margin against false positives.
