Subject: [PATCH] chore(engine): re-pin to 0.13.0 + refresh schema mirror
 (schema 1.7 -> 1.8)

Engine v0.13.0 (learn-content-engine#66 / PR #67): picture_choice.src
is now an anyOf of the classic assets/ path (<= 500 chars) OR an
inline base64 data URI (250000-char cap). Additive - all existing
path-src content validates unchanged. First pin bump since 0.12.2
with a REAL mirror content change (lesson + content-manifest schema
to x-schema-version 1.8, quality-rules $schema-version tracked).

Verified locally: validate_content.py all sets pass, make lint
(pinned engine gate 0.13.0) 0 errors, check_schema_drift.py in sync
against the 0.13.0 npm tarball.
