[Research] Create future plugin pack backlogs

[ashleyshaw]

Research Goal

Define backlog candidates for future plugin packs after the pilot is stable: block theme, block plugin, AI ops core, release ops, and talk/blog kit.

Parent epic: #285.

Background / Motivation

The first plugin should stay small, but the architecture needs clear future pack boundaries so favourite skills can be collected without scope creep.

Approach / Methods

• Review the PRD favourite skills backlog.
• Group candidate skills by plugin pack.
• Record priority, source, licence/trust notes, and dependencies.
• Identify what should not enter the governance pilot plugin.

Findings / Summary

To be completed after research.

Next Steps

Create follow-up issues only for packs approved after the pilot.
