# PR Status Sync Workflow
# ─────────────────────────────────────────────────────────────────
# Syncs PR lifecycle events with linked issues and project board.
#
# Status Transitions:
# - PR opened (ready) → Issues: "In Review"
# - PR draft → Issues: "In Progress"
# - PR merged → Issues: "To Deploy" + delete branch
# - PR closed (not merged) → Issues: "In Progress"
#
# Features:
# - Extracts linked issues from PR body
# - Updates project board status
# - Deletes merged branches
# - Fork-safe (skip writes for forks)
# - Debounced (10s delay to prevent loops)
