"""Управление пробелами в знаниях (research gaps).
Работает **только с PostgreSQL** — никакого веб-поиска. Поиск выполняет сама
модель встроенным инструментом \`web_search\` (SearXNG и автоматический
research-цикл убраны).
Жизненный цикл пробела:
open → researching → resolved | dismissed
Поля:
question — что нужно исследовать (формулировка)
reason — почему пробел обнаружен
priority — 0.0 .. 1.0 (больше = важнее)
status — open | researching | resolved | dismissed
