v0.8.0

Added

• A pinned external-source registry, cached update notices, reviewed refresh
  commands, and provider startup hooks now keep externally sourced skills
  traceable and easy to update without automatic merges.
• convert-documents-to-markdown adds a pinned, local document-ingestion
  fallback for office files and text PDFs.
• codebase-to-specs drafts explicitly inferred specifications, decision
  records, and architecture sketches from an existing codebase for human review.

Changed

• Four stale external skill sources were refreshed to their reviewed remote
  heads while local safety metadata and guidance were preserved.
• diagram-to-adr and diagram-to-likec4 supersede the Excalidraw-only skills.
  They add draw.io, embedded draw.io SVG, Mermaid, and appropriate BPMN support.
