chore: decompose finding GAP-01 into atomic implementation subtask

[esafwan]

What it does / Summary

Decomposes gap finding GAP-01 into an actionable, structured implementation subtask by generating plans/SweepGaps:GAP-01-plan.json.

What it solves / Motivation

• Formulates technical specifications for transitioning KOT delay alert generation from client-side UI timers to a backend scheduled pipeline.
• Ensures delayed unserved KOTs reliably trigger deduplicated notifications even when no KDS client screen is active.

Key Technical Changes

• Created plans/SweepGaps:GAP-01-plan.json specifying:
  • Objective: Build a scheduled backend alert pipeline for unserved KOTs, fix the URY KOT Items parenttype query filter, and support pluggable notification channels.
  • Acceptance Criteria: Automatic detection of unserved KOTs past warning threshold, deduplicated/repeatable alerts, correct parenttype query filter, scheduler hook registration, and test coverage.
  • Scope: ury/hooks.py, ury/ury/api/ury_kot_notification.py, patches, and URY KOT doctype files.
  • Metadata: Task type impl, difficulty 4, risk 4, uncertainty 3, priority 100.
