Add research rebuttal response pack

[absalonCRC]

/claim #16

Summary

• Adds a self-contained research-rebuttal-response-pack module for author rebuttal and revision planning.
• Converts reviewer findings into response rows with concern topics, response strategy, revision tasks, evidence requests, unresolved-risk flags, and readiness scoring.
• Clusters reviewer concerns and exports an editor-facing summary for resubmission decisions.
• Includes synthetic sample data, requirement mapping, tests, CLI demo, SVG, and short MP4 demo.

Distinctness

This is not another broad assistant suite, protocol/evidence trace packet, reviewer calibration bench, redline packet, or research-gap replication planner. The slice is specifically an author-facing rebuttal matrix plus editor-facing resubmission readiness packet.

Demo
