chore: decompose finding GAP-05 into atomic implementation subtask(

[esafwan]

What it does / Summary

Decomposes gap finding GAP-05 into an actionable, structured implementation subtask by generating plans/SweepGaps:GAP-05-plan.json.

What it solves / Motivation

• Prepares the implementation plan for surfacing top 3 favourite items for returning customers in POS v2.
• Ensures atomic scope boundaries and precise acceptance criteria prior to code changes.

Key Technical Changes

• Created plans/SweepGaps:GAP-05-plan.json specifying:
  • Objective: Surface top 3 favourite items for returning customers in POS v2 customer selection flow.
  • Acceptance Criteria: CustomerSelect.tsx invokes fav_items API, renders top 3 favourites, handles loading/empty/error states gracefully.
  • Scope: Target files across pos/src/ and ury/ury_pos/api.py.
  • Metadata: Task type impl, difficulty 3, risk 2, uncertainty 3, priority 80.
