/**
 * pi-loom: Temporal Query Parser
 *
 * Zero-LLM regex-based time-aware query parsing, aligned with Mem0 v3's
 * Temporal Reasoning feature. Extracts temporal intent from natural language
 * queries and maps them to SQL-compatible date ranges.
 *
 * Supported patterns:
 *   - "last week/month/year"     → relative date ranges
 *   - "today/yesterday"          → specific day ranges
 *   - "this week/month"          → current period
 *   - "recently"                 → last 7 days
 *   - "as of March 2025"         → absolute date anchor
 *   - "upcoming" / "planned"     → future/unexpired
 *   - "right now" / "currently"   → active + recent
