docs(adr): record the review outcomes for the Research registry grammar

- ADR-0004: add the "Amended by ADR-0028" note, following the ADR-0025
  convention.
- ADR-0028: correct Q5 (parse_status is gone), the skill count (38, not
  39), and the question order. Q7 records the anchored, format-only sha
  check. Q8 records the decision to commit real Vale fixtures. A new
  consequence covers path confinement and list rejection.
- CONTEXT.md: the `_Avoid_` entry means the bare noun, not the field.
- gates.md: correct the authored-hook counts after the corpus gate.
- create.md: a `none` entry backed by a reproduction must name committed
  fixtures in `Basis:`; use the `(digest: <full path>)` form.
- gitea-releases: use the `(digest: <full path>)` form.

 SUGGESTION (optional improvement). Provenance validation introduced observations
 that are worth surfacing but not actionable: a `references/*.md` file with no
