Replaces fast_scraper validation with efficient polling-based extraction
using the same navigation pattern as scrape_reviews:
- 10ms polling for consent handling (no fixed waits)
- 100ms polling for data extraction
- Exits early when data found
Supports multiple languages:
- Rating: stars/estrellas/étoiles/sterne/stelle
- Reviews: reviews/reseñas/avis/bewertungen/recensioni
- Handles comma decimals (4,8 -> 4.8)
Result: 6.3s to extract name, address, rating, total_reviews

The continue statement was skipping the card.style.display='none'
and card.innerHTML='' cleanup for cards already seen via API
interception. This caused DOM to grow unbounded during long scrapes.
Now ALL processed cards are hidden regardless of data source.

- Add fast_scrape_reviews() wrapper to scraper_clean.py for API compatibility
- Set window size (1200x900) in wrapper to ensure proper Google Maps rendering
- Update job_manager.py to import from scraper_clean instead of fast_scraper
- Production now uses clean scraper with:
- Hard refresh recovery when stuck after 8+ soft recovery attempts
- API interception + DOM parsing for complete data collection
- Automatic deduplication across refreshes
Tested: 589/589 reviews collected in 55s

When the scraper gets stuck (8+ failed soft recovery attempts), it now
does a hard page refresh and re-setups everything:
- Reloads the page
- Re-clicks reviews tab
- Re-sorts by newest
- Re-injects API interceptor
- Continues collecting with existing seen_ids for deduplication
Key changes:
- Extract page setup into reusable setup_reviews_page() function
- Add do_hard_refresh() that calls setup on refresh
- Trigger hard refresh after 8 failed soft recoveries
- Try hard refresh before timeout gives up completely
- Max 3 hard refreshes before truly giving up
- Reset recovery counter after successful hard refresh
This ensures the scraper can recover from browser issues, DOM detachment,
or other problems that soft recovery (scroll tricks) can't fix.

After sorting by newest, Google Maps may recreate DOM elements which
makes the Python scroll_container reference stale. Now re-find the
container after sorting to ensure we have a valid reference.

- Check total_reviews before recovery attempts
- Exit loop as soon as current_count >= total_reviews
- Reduces scrape time significantly (13s vs 56s for 247 reviews)

- Track DOM order for all reviews (review_order dict)
- Sort output by DOM position (preserves "Newest" sort order)
- API content + DOM order = best of both
- Remove click in recovery method 4 to avoid opening profile pages

- Fix API parser to use correct Google Maps response structure
- Review ID at [0], Author at [1][4][5][0], Rating at [2][0][0]
- Text at [2][15][0][0], Timestamp at [1][6]
- Use review_id as key for both API and DOM to avoid duplicates
- Prefer API data (original language, full text)
- Expand "More" buttons before sorting and during scroll loop
- Results: 246/247 full text (99.6%), down from 36/247 before

- Poll for up to 5s waiting for span[role="img"][aria-label*="review"]
- Element may not be present immediately after consent handling
- Tested: Soho Club 247/247 reviews in 31.4s with correct total
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Detect total BEFORE clicking reviews tab (element is on Overview)
- Use span[role="img"][aria-label*="review"] (robust, no class names)
- Extract count from aria-label (e.g., "260 reviews" → 260)
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Remove separators (AyRUI, TFQHme) adjacent to already-hidden cards
- Separators removed on next cycle, not immediately (preserves scroll)
- DOM growth reduced by ~50% during long scrapes
- Tested: 2000 reviews in 103s (19.3/s) with all features
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Use [data-review-id] + aria-label check for review cards
- Extract author from button[aria-label^="Photo of"]
- Use span[role="img"][aria-label*="star"] for rating
- Pattern matching for timestamp ("X time ago")
- Longest text span heuristic for review text
A/B tested: 100% match with old class-based selectors.
Survives Google's CSS class name changes.

Performance improvements:
- JS-based DOM parsing (single browser call vs Selenium round-trips)
- Batch flushing to disk every 500 reviews to free memory
- Hide parsed elements (display:none) to reduce DOM overhead
- Cycle timing instrumentation for debugging slowdowns
Results: 2826 reviews in 6.7min (7.1/sec) vs 2190 in 37min (1.0/sec)

Previous detection was matching wrong elements (partial counts).
Now sums "X stars, Y reviews" aria-labels for accurate total.
Fallback methods:
1. Sum star rating counts (most accurate)
2. Reviews tab text like "Reviews (247)"
3. Span with "X reviews" text
Tested: Soho Club 247/247 correctly detected

Key improvements:
- Background thread scrolling at 10Hz (0.1s intervals) for smooth continuous scroll
- JavaScript-based review ID collection (doesn't affect scroll position)
- API interception via injected fetch/XHR interceptor
- Total review count extraction from page
- Auto-stop when all reviews collected or timeout reached
The scroll issue was caused by Selenium's find_elements() affecting scroll
position. Using pure JavaScript for data collection keeps scroll pinned to bottom.

Major refactoring to achieve 100% review collection:
CONTINUOUS SCROLLING:
- Background thread scrolls NON-STOP at 5ms intervals (no gaps!)
- Main thread checks every 2s while scrolling continues
- Stops immediately when all reviews collected
- Solves the core problem: gaps between bursts caused Google to stop loading
SMART TIMEOUT:
- Gap-based: 3x average gap between review loads
- Initial timeout: 3x time since first load (or 15s default)
- Adaptive: evolves from conservative early timeout to smart gap-based
- Detailed logging shows timeout calculations
RESULTS:
- 100% completion (271/271) vs previous 91% (247/271)
- 3.5x faster (~17s vs 60s)
- Clean thread management with proper shutdown
REMOVED:
- All burst scrolling code (~100 lines)
- Scroll stuck detection (no longer needed)
- Dynamic sleep logic (replaced with continuous scrolling)

- Added fallback logic: if reviews tab not found with hl=en, retry without locale override
- Added multilingual keywords for reviews tab (Lithuanian, Russian, etc.)
- Fixed structural pattern matching to search only within reviews pane, not entire page
- Added Lithuanian date keywords (dienų, savaitės) to date pattern matching
- All three selector strategies now scoped to reviews pane for accuracy
Issue: Lithuanian hospital still extracting 0/271 reviews
Root cause: Reviews elements not found even within pane after tab click
Next steps: Need manual inspection of actual page structure on Lithuanian locale
BREAKING IMPROVEMENTS:
1. Early Detection for No Reviews:
- Check for "no reviews" messages in 11+ languages before scraping
- Detect disabled reviews tabs and aria-labels with 0 reviews
- Return early with success when no reviews exist (saves time)
- Prevents wasted scraping attempts on businesses with no reviews
2. Structural Pattern Matching (Class-Agnostic):
- STRATEGY 1: Try known CSS selectors (div.jftiEf.fontBodyMedium, etc.)
- STRATEGY 2: Structural matching - find containers with review-like structure
* Looks for elements containing: author + rating + text + date
* Counts elements with 3+ review indicators (robust, works across layouts)
- STRATEGY 3: Use role="article" with review content detection
- Falls back through strategies automatically
3. Less Script-Dependent Selectors:
- Uses aria-label attributes (more stable than CSS classes)
- Uses role attributes (semantic HTML)
- Searches for structural patterns (author img + rating span + text span)
- Works across different Google Maps page layouts and languages
4. Frontend Improvement:
- Hide "Open Analytics Dashboard" button when reviews_count is 0
- Only show action buttons for completed jobs with reviews
TECHNICAL DETAILS:
Structural Matching Logic:
- Scans all divs for review indicators:
* hasAuthor: img with photo/avatar in src
* hasRating: aria-label containing "star" or "rating"
* hasText: span with 20+ characters
* hasDate: text matching date patterns (day/week/month/year)
- Element is a review if it has 3+ of these indicators
Early Detection Patterns:
- Checks page text for: "no reviews yet", "be the first to review", etc.
- Checks for "0 reviews" patterns in text and aria-labels
- Checks if reviews tab is disabled or aria-disabled
Benefits:
- Works on Lithuanian hospital page (was getting 0/271 reviews)
- Handles regional Google Maps variations automatically
- Faster exit for businesses with no reviews
- More reliable across Google Maps UI updates
- Better UX: no empty analytics dashboard for 0-review jobs

- Now tries: div.jftiEf.fontBodyMedium, div.jftiEf, div[data-review-id], etc.
- Automatic selector detection logs which selector works for debugging
Test results:
- Successfully scraped 550 reviews in 150.53s without crashes
- Memory management prevents Chrome tab crashes during heavy scraping
