fix(kyberforge): unblock the scaffold and finish the #125 and ADR-0022 edits

Three related half-applied changes from #130, each leaving the corpus in a state its own
documentation contradicts.

Why:
- `assets/templates/SKILL.md` shipped `metadata:` fully commented out, and `new-skill.sh` only
  substitutes SKILL_NAME. Every scaffolded skill therefore lacked the `metadata.version` ADR-0022
  made mandatory and was blocked at first commit by the very hook this PR added. The commented
  example also read `"1.0"` — neither the `0.1.0` new-skill seed nor valid semver.
- `agent-audit/references/scope-project-user.md` still joined `disable-model-invocation` and
  `user-invocable` with a slash — #125's defect verbatim — while pointing the reader at the file
  this PR had just corrected to say the opposite.
- ADR-0022 required the "when present" bump conditional dropped and `metadata.version` moved into
  create.md's required list. It was dropped from SKILL.md but left in README.md, and the field was
  edited in place under a heading that still authorises removing it entirely.

Implementation notes:
- The template emits `metadata: version: "0.1.0"` live, captioned as required, with the optional
  keys left commented. `new-skill.bats` gains a case asserting a live key and three-part semver, so
  this cannot regress.
- `description-quality.md` now asserts only what the vendored Copilot research supports: two fields
  with opposite defaults, and the retired `infer` replaced by the pair rather than by either alone.
  The unsupported negative it previously stated as fact is gone.
- The `1.0.0` retrofit seed is stated in improve.md and retrofit.md, which the retrofit flow
  actually reads — create.md, where it lived, is unreachable from that path. The compression item
  moved out of the file-churn checklist, whose preamble excluded the wording-only change it covers.
- Executable git commands in these three skills now carry the ADR-0023 rtk prefix.
