/**
 * On-task-complete hook for StackMemory
 * Triggers when a task is marked as done in Claude Code.
 *
 * Actions:
 * 1. Auto-updates PROMPT_PLAN.md checkboxes (fuzzy match on task keywords)
 * 2. Syncs Linear tasks (if STA-* identifier present)
 * 3. Logs to ~/.stackmemory/logs/hook-errors.log on failure (non-blocking)
