chore(agents): sync review-discussions skill + workflow + command (orthogonal to Group A)

These files were dirty in the worktree at session start and survived all
R3/R4/R5 fix work untouched — they belong to the review-discussions skill
and are independent of the AgentBridge/Traffic Inspector implementation.
Committing here so the worktree is clean for removal.

+GraphQL caps each `discussions` query at 50 nodes — repos with more than 50 open discussions **must paginate**. Loop with `first: 50, after: $cursor` until `pageInfo.hasNextPage` is `false`. Skipping pagination silently drops the older half of the backlog, which is exactly where most stale-candidates and unanswered follow-ups live (regression observed 2026-05-28: page-1-only fetch missed 5 follow-ups and 4 stale candidates ranging from 23d to 56d).
