feat(engine): ext.struct typed-records built-in; close engine implementation (WP-0014 T6)

engine/extensions/struct.py: ext.struct (typed records) — in-text frontmatter
parse + ON_WRITE validation (allowed-fields, content-preserving), ON_READ tags
PageShape.TYPED_RECORD, ON_PROFILE raises structured-payload. Proves the framework:
feature absent when off (opaque prose, honest profile), present + profile-reflected
when on; works through InformationSpace edit. SCOPE updated. 6 tests, 107 total,
~97% coverage, pyflakes clean. Marks T6 + SHARD-WP-0014 done.
