v0.9.0

Added

• Sources pagination and filtering. Sources index now paginates (25 per page, configurable) with Previous/Next controls. Dropdown filters for Status, Health, Format, and Scraper Adapter auto-submit on change. Active filters shown as dismissible badges. Text search and dropdown filters compose as intersection and persist across pagination.
• Per-source scrape rate limiting. New min_scrape_interval column on sources allows time-based throttling between scrapes. Global default (1.0s) configurable via config.scraping.min_scrape_interval. Per-source overrides via the column value. ScrapeItemJob and Enqueuer check last scrape time from scrape_logs and re-enqueue with delay when rate-limited.
• Word count metrics. New feed_word_count and scraped_word_count columns on item_contents. Feed content is HTML-stripped before counting; scraped content counted as-is (readability-cleaned). Separate "Avg Feed Words" and "Avg Scraped Words" columns on sources index. Separate "Feed Words" and "Scraped Words" columns on items index and source detail items table. Backfill rake task: source_monitor:backfill_word_counts.

Fixed

• Show created_at fallback when published_at is nil in items table.
• Handle source destroy failures with proper error responses instead of silent failures.
• UI fixes: navigation warning indicator positioning, toast container placement, dashboard table alignment.
• N+1 query fix: source detail items table now uses includes(:item_content).

Testing
