chore: decompose finding GAP-03 into atomic implementation subtask(

[esafwan]

What it does / Summary

Decomposes gap finding GAP-03 into an actionable, structured implementation subtask by generating plans/SweepGaps:GAP-03-plan.json.

What it solves / Motivation

• Formulates technical implementation requirements for subscribing POS v2 Table and Orders views to Frappe realtime socket events (reload_ro).
• Ensures live table occupancy and order status updates across POS clients without manual page refreshes.

Key Technical Changes

• Created plans/SweepGaps:GAP-03-plan.json specifying:
  • Objective: Implement realtime order reload listeners and cache invalidation in POS v2 table and order pages.
  • Acceptance Criteria: Register and clean up reload_ro listeners in Table.tsx and Orders.tsx, invalidate room/table caches, and trigger refetches without accumulating duplicate handlers.
  • Scope: pos/src/pages/Table.tsx, pos/src/pages/Orders.tsx, and related POS/core modules.
  • Metadata: Task type impl, difficulty 3, risk 3, uncertainty 3, priority 88.
