Fix type mismatch between MediaCrawler model (int) and PostgreSQL schema (VARCHAR) for timestamp fields: - created_time - updated_time - publish_time This prevents "invalid input for query argument" errors when crawling Zhihu content and storing to PostgreSQL database.
- Add null checks in get_video_url_arr() for missing video fields - Add int() type casting for numeric fields in update_xhs_note_comment() (sub_comment_count, like_count, parent_comment_id) - Add tracking_models.py for keyword tracking schema - Update config for PostgreSQL and session persistence settings
Lower the HackerNews network variance check from 30ms to 20ms to reduce flaky test failures due to network response time fluctuations.
