chore(skills): bump metadata.version for the Research doc migration

Raise the PATCH version of each skill whose references/sources.md,
references, or validator changed in the Research registry migration, as
ADR-0022 requires. factory-audit and skill-author changed behaviour and
docs; the rest changed provenance metadata only.
