Resolve conflicts against the new native google-maps actor + repo-wide
ruff-format pass:
- Keep legacy webcrawler KB indexer + its test deleted (modify/delete).
- test_validators: keep WEBCRAWLER case removed (validator gone).
- test_fetch_resilience: keep platforms.youtube import path (our reorg).
- Relocate google_maps actor + tests scrapers/ -> platforms/ to match the
reorg convention (youtube already there); rewrite imports + fixture paths.
- Add missing __init__.py across the capabilities/ test subtree so duplicate
test basenames get unique module paths under importlib mode.
Note: google_maps fixture-backed tests error on ci_mvp too (fixtures/*.json
never committed upstream) - pre-existing, out of scope here.
