- Fix OSRM client to use semicolons (not commas) for source/destination
indices in /table API requests. Commas caused "Query string malformed"
errors for any batch with more than one origin.
- Add error handling in poi_distance_calculator for unreachable routing
engines (OSRM/OTP). Connection failures now log an error and skip the
mode instead of crashing the entire Celery task.
The crawler subdirectory was the only active project. Moving it to the
repo root simplifies paths and removes the unnecessary nesting. The
vqa/ and immoweb/ directories were legacy/unused and have been removed.
Updated .drone.yml, .gitignore, .claude/ docs, and skills to reflect
the new flat structure.
