fix: pre_chunks schema + TMDb movie name extraction

- pre_chunks: add chunk_type, text_content columns; drop NOT NULL on
  coordinate_type/coordinate_index (INSERT statements reference these
  columns but CREATE TABLE was missing them)
- run_migrations: add ALTER TABLE for existing databases
- extract_movie_name: filter noise words (youtube, fps, 24fps, 1080p,
  pure digits) so 'Charade_YouTube_24fps' → 'Charade'
- run-server-3002.sh: add companion worker startup (matching 3003 script)
