Normalize vulnerability summaries and preserve markdown details in jsrepository-master

[Copilot]

Some vulnerability entries used multiline markdown in summary, and a subset of generated summaries began with an artificial Summary prefix. This PR standardizes summary text for machine/human readability while preserving full advisory content.

• Summary normalization

  • Rewrote affected summary fields to plain inline text (no markdown section blocks/newline-heavy formatting).
  • Removed leading Summary prefixes from generated summaries where present.
  • Kept multi-sentence summaries when useful, as long as they remain plain text.

• Details preservation

  • Moved original multiline markdown content from summary into a new sibling details field on the vulnerability object.
  • Retains full advisory narrative without polluting concise summary output.

• Schema + type support

  • Added optional details to vulnerability validation in node/src/repo.ts.
  • Added details?: string to Vulnerability in node/src/types.ts.

• Repository artifact sync

  • Regenerated derived repository JSON files to keep all versioned outputs consistent with jsrepository-master.json.
