chore(sync): include Plan 3 plan-doc in Claude sync

Adds dev-docs/superpowers/plans/2026-05-17-gui-redesign-tier1-primitives.md
to .claude-sync.conf so the Plan 3 doc is visible to Claude Chat for
drift detection and review during Plan 3 execution.

Glob support remains the right BACKLOG item (TECH-SYNC-001 candidate)
to eliminate manual conf maintenance for future plans.
