v1.3.0 — claude-drift-triage component

Adds claude-drift-triage to the catalog. LLM-augmented schema
drift triage: a consumer's drift command emits diffs; the
component sends them to Claude for classification and concrete
next-step suggestions; optionally opens a GitLab issue with the
triage.

No breaking changes; existing components unchanged. CI image
unchanged (curl + jq + bash already present).

Validated via glab api ci/lint against a synthetic consumer
(see commit 0d04dfa).
