v0.1.1

Fixed

• Date presets ignore DEFAULT_TIMEZONE at month boundaries: startOfDayInTz day-change detection failed when timezone offsets crossed month boundaries (e.g. today in America/Mexico_City resolved to wrong date when UTC had already crossed into the next month)
• Explicit date-only from/to strings parsed as UTC: date-only strings (YYYY-MM-DD) are now interpreted as start/end of day in the configured DEFAULT_TIMEZONE instead of UTC midnight

Added

• Integration test Phase 7 — Timezone awareness (4 tests)
• 10 new unit tests for month boundary and date-only cases
