v1.3.0

This release makes the finished document self-documenting and gives you control over the contact sheets and transcript.

Added

• Source recorded in the document. Each video's analysis shows a readable "Source:" line (the original URL or local path) right under its title, so the document records exactly what was analyzed.
• Standalone transcript file. When a transcript is available, the pipeline writes a human-readable transcript.txt ([mm:ss] text per line) and exposes its location in the manifest.
• Optional transcript appendix. The document builder can append the full transcript, reading the transcript.txt directly by path so long transcripts don't bloat anything.
• Keep-artifacts options at delivery. You can now choose to include the contact sheet(s) and/or the full transcript as in-document appendices, and to keep standalone copies (clearly named, collision-safe) next to the finished document even when the working files are cleaned up.
