LogCondition class sealed

One selection condition for entries: LogFilter decomposes into them (LogFilter.conditions), and an entry matches the filter if it matches all of its conditions.

The set of conditions is closed (sealed), and the meaning of each is defined here, in matches. A store with its own query language (SQL) translates conditions with an exhaustive switch without a default branch: a new condition becomes a compile error there, not a silently skipped selection.

for (final condition in query.filter.conditions) {
  switch (condition) {
    case LogAfterCondition(:final time): where.add('time > ${micros(time)}');
    // … a branch per condition
  }
}
