Five §"..." cross-refs survived the main sweep because they live
inside jsonc Schema-comments — clause-5 fence-skip would treat any
[label](path) there as literal text, not as a navigable link.
Instead of touching the schema-comment style (it is self-documenting
where it sits, against the field it qualifies), this commit adds
prose paragraphs just outside the fence that turn the same
cross-references into real links:
- Before the Def jsonc block: pointer to memory-model.md
(canonical-form rule for cross-module class/type names) and
embedding-abi.md (exported fn surface).
- Before the Type jsonc block: pointer to memory-model.md for
Type::Con.name scoping and Type::Fn parameter-mode metadata.
Also re-phrases an intra-file §"Str ABI" self-reference in
str-abi.md to "the Str ABI table below" — file-only granularity
makes a self-link sense-less; the reader wants intra-file
direction, which prose carries fine without a link.
Tests: design_index_pin (5/5) + docs_honesty_pin (5/5) stay green.
