Follow-up pushed to strengthen the scientific-formatting and reference-manager parts of issue #12:

• added deterministic formatting summary for Markdown, LaTeX/equations, code-language metadata, notebook-cell support, references, citation resolution, and publication templates
• expanded the sample document with a LaTeX block, Zotero-style reference metadata, citation key, and Nature Methods template
• updated tests, demo output, README, and requirement map

Verification after the update:

• cd collaborative-editor-governance && npm run check
• cd collaborative-editor-governance && npm test
• cd collaborative-editor-governance && npm run demo
• git diff --check

Follow-up pushed in 76dc87c to strengthen the real-time editor scope for #12 with offline collaboration conflict evidence.

Added:

• queued offline client operations in the sample fixture
• deterministic offline rebase reporting
• stale block-version detection with safe conversion to suggestions instead of overwriting live edits
• section-lock conflict detection for reconnecting edits
• missing review/comment target detection
• restore-ready snapshots and audit hashes for conflict reports
• demo output and requirement-map coverage for the offline/local caching recovery path

Verified locally:

• npm run check
• npm test
• npm run demo
• git diff --check

Added a short demo video artifact for Algora/reviewer convenience:

• Demo video: https://raw.githubusercontent.com/kkudumu/SCIBASE.AI/kkudumu/collab-editor-governance-12/collaborative-editor-governance/docs/demo.mp4
• Existing GIF remains at collaborative-editor-governance/docs/demo.gif
• CLI demo remains npm run demo

This is the same deterministic demo flow already covered by the local tests and README, now available as an MP4 video artifact.

Updated the existing demo video with narrated voiceover explaining every major change in this PR: scientific document blocks, Markdown and LaTeX metadata, reference handling, comments, suggestions, tasks, section locks, snapshots, presence, and offline conflict evidence. The PR's existing demo-video link now points to the narrated MP4.
