v0.13.0 — 2026-08-17

Highlights

• Editorial diagrams — new kit architecture diagram (HTML source) and a redesigned Personal Dev Tutor architecture overview; README hero now shows a real stack diagram with CI and measured eval results.
• CI hardening — validate checks profile skill lists resolve and stay in sync and guards against re-vendoring third-party skills; CI runs every test:* contract suite.
• Fixes — Personal Dev Tutor contract test targets the new diagram source (contract-tests green again); Hermes workhorse link-signal window hardened.
• Housekeeping — third-party skills no longer vendored (licenses recorded for the 17 pinned skills); one shared tutor-home resolution helper; CONTRIBUTING.md / SECURITY.md and a regenerated social preview.
