fix: replace fabricated LASR Core description in AgentSkill catalog

The previous commit fixed the "Also known as" line but left the Core
field describing the invented "lightweight architecture description
framework" with the fabricated Layers/Aspects/Solution
Strategy/Rationale expansion. The Core field now describes the real
review method (Lean Mission Statement, Evaluation Criteria, Risk-based
Review, Quality-focused Analysis, Result Diagram, workshop format).

-- **Core:** Lightweight architecture description framework — describe a system through four lenses: Layers (structural decomposition), Aspects (cross-cutting concerns), Solution Strategy (key technology and design choices), Rationale (documented reasoning behind decisions); pairs naturally with arc42 and ADRs
+- **Core:** Lightweight review method for efficient software reviews — uncovers weaknesses and challenges architectural ideas; more streamlined than ATAM. Key elements: Lean Mission Statement (shared vision), Evaluation Criteria (quantified quality attributes), Risk-based Review, Quality-focused Analysis, LASR Result Diagram (objectives vs. assessment), workshop format (moderated team event with LASR-Cards). Community-driven and free to use (lasr-reviews.org)
