8bf1f9e24b Add regression test for listing_type=None including sold listings
Adds test_listing_type_none_includes_sold() to verify that when listing_type=None, sold listings are included in the results. This prevents regression of issue #142.

79b2b648f5 Fix sold listings not included when listing_type=None (issue #142)
When listing_type=None, sold listings were excluded despite documentation stating all types should be returned. This fix includes two changes:

1. Explicitly include common listing types (for_sale, for_rent, sold, pending, off_market) when listing_type=None instead of sending empty status parameter
2. Fix or_filters logic to only apply for PENDING when not mixed with other types like SOLD, preventing unintended filtering

Updated README documentation to accurately reflect that None returns common listing types rather than all 8 types.

c2f01df1ad Add configurable parallel/sequential pagination with parallel parameter
- Add `parallel: bool = True` parameter to control pagination strategy
- Parallel mode (default): Fetches all pages in parallel for maximum speed
- Sequential mode: Fetches pages one-by-one with early termination checks
- Early termination stops pagination when time-based filters indicate no more matches
- Useful for rate limiting and narrow time windows
- Simplified pagination logic by removing hybrid first-page pre-check
- Updated README with usage example and parameter documentation
- Version bump to 0.8.4
- All 54 tests passing
