Create a new issue-thread interaction UI (developer skill)

This skill walks a Paperclip contributor through introducing a new issue-thread interaction kind from shared contract to issue-detail wiring, helpers, and docs. It is intentionally a developer/maintainer skill: the audience is a human or coding agent making code changes inside paperclipai/paperclip, not the operational agents that run inside a deployed Paperclip company.

When to use

• A new interaction kind is being introduced (compact picker, structured rating, in-thread approval card, etc.).
• An existing interaction needs a parallel variant with a distinct payload shape, validation, or resolution outcome (and ask_user_questions is the wrong fit because option count, target binding, or result shape differs).
• A reviewer asks for "the same audit, staleness, supersede, and continuation semantics as the other interactions" on a new card.
