- all.py: replace sequential loop with graphlib.TopologicalSorter + ThreadPoolExecutor
- EXTRACTORS dict declares (func, [deps]) — self-documenting dependency graph
- 8 extractors run in parallel immediately; availability starts as soon as
tenants finishes (not after all others complete)
- max_workers=len(EXTRACTORS) — all I/O-bound, no CPU contention
- playtomic_tenants.py: add proxy rotation via make_round_robin_cycler
- no throttle when PROXY_URLS set (IP rotation removes per-IP rate concern)
- keeps 2s throttle for direct runs
- _shared.py: add optional proxy_url param to run_extractor()
- any extractor can opt in to proxy support via the shared session
- overpass_tennis.py: fix query timeout (out body → out center, timeout 180 → 300)
- out center returns centroids only, not full geometry — fits within server limits
- playtomic_availability.py: fix CIRCUIT_BREAKER_THRESHOLD empty string crash
- int(os.environ.get(..., "10")) → int(os.environ.get(...) or "10")
